CANADIAN EQUIPMENT LIMITATIONS
Notice: The Canadian Industry and Science Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective,
operational, and safety requirements. The Department does not
guarantee the equipment will operate to the user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an
acceptable method of connection. In some cases, the company's
inside wiring associated with a single line individual service may
be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above conditions may not prevent degradation of
service in some situations.
Repairs to certified equipment should be made by an authorized
Canadian maintenance facility designated by the supplier. Any
repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical
ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural
areas.
Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection
authority, or an electrician, as appropriate.
The Load Number (LN) assigned to each terminal device denotes
the percentage of the total load to be connected to a telephone
loop which is used by the device, to prevent overloading. The termination on a loop may consist of any combination of devices
subject only to the requirement that the total of the Load Numbers
of all devices does not exceed 100.

Chapter 1
Introduction
PRODUCT OVERVIEW
The ADTRAN Router Option Module installs in the option slot of
the TSU muliplexer family of products and provides integrated rout-
ing capability access frame relay or point-to-point networks.
Basic Functions of Router Option Module
The Router Option Module provides the following basic functions:
LAN Bridge
Bridging provides a point-to-point connection between two local
area networks (LANs). The bridge learning function scans the
source and destination media access control (MAC) addresses of all
packets on its LAN and determines which packets should be trans-
mitted over the T1 link. Applications include connectivity between
single users or small offices to corporate LANs. The Router Option
Module uses the Spanning Tree Algorithm (IEEE 802.1d-ISO/
IEC10038), which provides a loop-free topology and redundancy.
IP Router
The Router Option Module can function as an IP router using the
Routing Information Protocol (RIP) for advertising and learning
routes among other routers. Static routes may also be entered into
the routing table.
IPX Router
IPX routers and services can be exchanged between the Router Op-
tion Module and other devices using RIP and Service Advertising
Protocol (SAP). Watch dog serialization filtering and spoofing can
permit the ISDN to be idle during no application traffic periods.

Chapter 1: Introduction
Network Address Translation (NAT)
Single networks can connect to the Internet with this function. The
Router Option Module translates outgoing IP packets over the T1 to
the IP router at the Internet Service Provider. Popular Internet applications are supported.
PPP or Frame Relay
The layer 2 protocol used to transfer packets can be PPP or Frame
Relay (RFC 1490). PPP allows a point-to-point connection, whereas
Frame Relay can provide up to ten permanent virtual circuits.
Routing and Bridging with the Router
Option Module
The Router Option Module is a Router and Transparent Learning
Bridge. Its features can be easily configured and used, once several
basic concepts are understood.
Factory Default
The Router Option Module comes from the factory configured for
MAC Bridging, IP routing, and IPX routing with no filters or connection information defined. An IP address of 10.0.0.1 with a network mask of 255.255.255.0 is preloaded. The factory default layer 2
configuration is PPP, which provides the least amount of reconfiguration due to its negotiation-oriented nature.
Bridging
IP Routing
1-2
In Bridge Mode, the Router Option Module can be used to connect
two LAN segments. In this mode, all protocols are supported because they are transported across the T1 link at the MAC layer. The
Spanning Tree Algorithm can be used to guarantee a loop-free topology. MAC- save addresses are “learned” by each Router Option
Module to prevent non-WAN packets from being bridged.
The Router Option Module operates as an IP router when the Con-
figuration/IP/IP Router/Mode option is configured to On. In PPP
mode, the Router Option Module uses an IP unnumbered WAN in-
Router Option Module User Manual 61200350L1-1
terface. The IP address and mask assigned to the unit’s LAN inter-
face apply to all routing and IP operations for the unit.
In Frame Relay mode, each PVC can be specified as numbered or
unnumbered links. If a default gateway is specified on the network
of the Ethernet interface, the unit attempts to reach the gateway
through that interface. If no default gateway is specified (i.e.,
0.0.0.0.), the WAN interface becomes the default gateway (recom-
mended for remote applications when there are no other routers on
the remote LAN).
IPX Routing
Network routes and services are learned and advertised using No-
vell’s RIP and SAP.
Concurrent Routing and Bridging
The Router Option Module can route IP and IPX as well as bridge
nonIP/IPX packets simultaneously. The PPP profile will, by default,
negotiate PPP network protocols to support the transmission and
reception of IP, IPX, and Bridge packets. If the PPP peer does not ac-
cept a protocol, the Router Option Module will fall back to any com-
bination of routing and bridging.
Chapter 1: Introduction
Network Address Translation Mode (NAT)
NAT is a special mode of operation in which the Router Option
Module obtains a dynamically assigned IP address from the peer
router (typically an Internet Service Provider). This allows a net-
work of computers to appear as a single IP address.

Chapter 4: Configuration Overview
IP/DNS
The Domain Name Server parameters used by the Router Option
Module are specified here. The DNS server addresses can be exchanged between PPP peers. When a connection occurs and IPCP is
negotiated, the Router Option Module will get the DNS server addresses from the PPP peer.
If the configured DNS server addresses (Server 1 and Server 2) are
all zeros, the addresses from the PPP peer are used. In NAT mode,
the PPP peer’s DNS addresses are always used. The DNS addresses set
in Server 1 and Server 2 are offered to a PPP peer, if so requested.
DNS/Domain Name
Write security: 3; Read security: 5
This is a text string used to represent the domain name used by the
Router Option Module.
DNS/Server 1

This is the IP address for the primary DNS device. It is the first server to which domain name requests are sent.
DNS/Server 2
Write security: 3; Read security: 5
This is the IP address for the secondary DNS device. It is used as a
back-up in case the primary address does not respond to the request.
IP/UDP Relay
The Router Option Module can be configured as a relay agent for
UDP broadcast packets. Normally, a router will not forward UDP
broadcast packets. However, many network applications use UDP
broadcasts to configure addresses, host names, and other information. If hosts using these protocols are not on the same network segment as the servers providing the information, the client programs
will not receive a response without enabling the UDP relay agent.

UDP Port 1, UDP Port 2, and UDP Port 3 are used for specifying
UDP ports to be relayed. These fields only apply when UDP Port
Type is set to Specified.
IP/Proxy ARP
Write security: 4; Read security: 5
This feature allows the network portion of a group of addresses to
be shared between several physical network segments. The ARP
protocol itself provides a way for devices to create a mapping between physical (i.e., Ethernet) addresses and logical IP addresses.
Proxy ARP makes use of this mapping feature by instructing a router to answer ARP requests as a “proxy” for the IP addresses behind
one of its ports. The device which sent the ARP request will then
correctly assume that it can reach the requested IP address by sending packets to the physical address that was returned to it. This technique effectively hides the fact that a network has been (further)
subnetted.
61200350L1-1 Router Option Module User Manual

Chapter 4: Configuration Overview
If this option is set to Yes (def), when an ARP request is received on
the Ethernet port, the address is looked up in the IP routing table. If
the forwarding port is not on the Ethernet port and the route is not
the default route, the Router Option Module will answer the request
with its own hardware address.
If set to No, the Router Option Module will only respond to ARP requests received for its own IP address.

run over Ethernet to be forwarded. Bridging can run concurrently
with the IP and IPX routing. However, when packets are bridged
across a WAN connection, the following rules apply:
• When IP routing is active, IP packets (which include ARP packets) are not bridged.

Bridge/WAN IP Bridge
When IP routing is active, the Router Option Module will allow another WAN device to bridge IP packets to itself by using PPP BCP.
Normally, two IP routers would negotiate PPP IPCP to exchange IP
packets.
However, if a device can only support PPP BCP, IP packets are encapsulated by the device as bridge packets. The Router Option
Module can treat the WAN IP Bridge as a virtual Ethernet port connected only to a WAN device which has negotiated PPP BCP. This
menu allows the IP parameters for this virtual Ethernet to be set up.

Write security: 1; Read security: 2
The PPP peer can be authenticated using three standard methods:

2. CHAP (Challenge Handshake Protocol)
3. EAP (Extensible Authentication Protocol).
The strength of the authentication is determined in the following order:
1. EAP
2. CHAP
3. PAP (where EAP is the strongest and PAP is the weakest)
PAP is a clear-text protocol, which means it is sent over the PPP link
in a readable format.
Do not allow highly sensitive passwords to become compromised using this
method.
CHAP and EAP use a one-way hashing algorithm which makes it
virtually impossible to determine the password. EAP has other capabilities which allow more flexibility than CHAP.
The following selections are possible:
PAP, CHAP or EAP (def) - The Router Option Module will ask for
EAP during the first PPP LCP negotiation and allow the PPP peer to
negotiate down to CHAP or PAP.
CHAP or EAP - The Router Option Module will ask for EAP during
the first PPP LCP negotiation and allow the PPP peer to negotiate
down to CHAP but not PAP.
EAP - The Router Option Module will only allow EAP to be negotiated. If the PPP peer is not capable of doing EAP, then the connection will not succeed.

Frame Relay
(also available via Front Panel)
Frame Relay is a connection-oriented service requiring circuits to be
configured by your carrier to establish a physical link between two
or more locations. Multiple virtual circuits (which appear as virtual
point-to-point links) can be run through the same physical connection.
There are two types of virtual circuits supported in Frame Relay:
Virtual Circuit Types Description
Permanent Virtual Circuits
(PVC)
PVCs are like dedicated point-to-point
private lines.
Since the physical connection is always
there in the form of a leased line, call
setup and tear down is done by a carrier via a network management system.
Virtually all Frame Relay communication is done using PVCs.
Switched Virtual Circuit
(SVC)
SVCs require setup and tear down and
are generally not available from Frame
Relay carriers.
The Router Option Module supports PVCs only.
The Data Link Connection Identifier (DLCI) number identifies each
virtual circuit within a shared physical channel.

The Frame Relay maintenance protocol is used on the WAN port.
The maintenance protocol is used to send link status and virtual circuit information between Frame Relay switches and other devices
(such as routers) that communicate with them. Possible choices are
listed below.
Annex D(def) An ANSI standard that is most commonly used
in the US.
Annex A The CCITT European standard.
LMI Used by some carriers in the U.S.
Developed by a vendor consortium and known
as the “consortium” management interface spec-
ification.
Static Select when there is no Frame Relay switch in
the circuit. The DLCIs are assigned in the DLCI
Mapping and must be the same for the device it
will communicate with.
Frame Relay/Polling Frequency
Write security: 3, Read security: 5
This parameter is the interval that the Router Option Module polls
the Frame Relay switch using the maintenance protocol selected
above. The Router Option Module is required to poll the Frame Relay switch periodically to determine whether the link is active. The
value is in seconds and ranges from 5 to 30 seconds.
Frame Relay/DLCI Mapping
This menu allows each DLCI to be mapped to a particular protocol.
Each protocol parameter can be individually configured for each
DLCI. By factory default, the DLCI map is empty.
When empty and a maintenance protocol other than static is used,
the Router Option Module will poll the switch to determine which
DLCIs are active. These active DLCIs will attempt to determine the
IP and IPX addresses on the other end of the virtual circuit using Inverse ARP (IARP). If there is a response, the network learned will be
added to the router tables and the virtual circuit will be treated as an
unnumbered interface. Bridge mode is not attempted in this case.

Chapter 4: Configuration Overview
When more than one DLCI mapping is listed, the Router Option
Module will try to match the DLCIs learned from the Frame Relay
switch with the DLCI values in the map. If there is a match, the protocols specified in the map are used. However, if an active DLCI is
not in the list, the Router Option Module falls back to using IARP as

destined to be transmitted out a particular bridge group are copied
and transmitted individually out each DLCI in the bridge group.
However, incoming bridge packets received from one DLCI are not
retransmitted out the other DLCIs in the same bridge group. Any
device in the bridge group must transmit to each DLCI. This requires a fully meshed circuit, meaning each device has a virtual circuit to each other.

IP/Mode
Write security: 3; Read security: 5
When set to On (def), this connection profile negotiates PPP IPCP
with the PPP peer for exchanging of IP packets.
IP/NAT
Write security: 3; Read security: 5
The Router Option Module can perform Network Address Translation. This feature is most widely used when connecting to the Internet. The Ethernet network can consist of private network numbers.
When this profile is connected, all IP addresses on the Ethernet side
are translated into the one real IP address negotiated with the PPP
peer (ISP). Multiple stations on the Ethernet side can access the Internet simultaneously. See the section IP/NAT on page page 4-7 for
more global options.
When set to On, the Router Option Module to perform NAT.
When set to Off (def), the unit will route across the connection nor-
mally.
IP/Route
The IP parameters are configured in this menu. Usually the Router Option Module will automatically discover the PPP peer’s networks using PPP
IPCP and/or RIP.
Route/IP/Net
Write security: 3; Read security: 5
The PPP peer’s IP address or network can be set here, if known.
Leaving this at 0.0.0.0 means that the Router Option Module will determine the PPP peer’s IP and network using the PPP IPCP.
Route/Netmask
Write security: 3; Read security: 5
This network mask is applied to the IP/NET address for determining the PPP peer’s network. If left as 0.0.0.0, a standard network
mask is used.

When set to On (def), the connection profile to negotiate PPP IPXCP
with the PPP peer for exchanging of IPX packets.
IPX/Remote Network
Write security: 3; Read security: 5
A nonzero value in this remote network number will allow the
Router Option Module to add a route to the PPP peer’s network to
the routing table.
The Router Option Module normally will treat the WAN network as
an unnumbered link. This is usually referred to as being a “halfrouter.” However, a PPP peer which wants to assign a network address to the WAN link can do so, in which case the Router Option
Module will go into “full-router” mode.
IPX/Triggered
Write security: 3; Read security: 5
When set to Yes, only IPX RIP and SAP updates are sent when the
routing or service table has changed and learned routes are not
“aged.”
When set to No (def), updates are sent periodically based on the RIP
and SAP timers set in Configuration/IPX/RIP Timer and Configu-
ration/IPX/SAP Timer.
IPX/Type 20 Packets
Write security: 3; Read security: 5
For certain protocol implementations, like NetBIOS, to function in
the NetWare environment, routes must allow a broadcast packet to
be propagated throughout the IPX networks.
61200350L1-1 Router Option Module User Manual
4-39
Chapter 4: Configuration Overview
The Type 20 IPX packet is used specifically for this purpose. This
causes special handling of this packet by the Router Option Module.
When a router receives this type of packet, it rebroadcasts it across
all interfaces except the one it is received on and includes the network number of that interface in the data portion of the packet.
The IPX Router Specification from Novell notes that Type 20 packets
should not be propagated across slower links with bandwidths of
less than 1 Mbps (like ISDN). However, when set to Pass (def), the
Router Option Module will allow these packets to propagate over
the WAN connection. This facilitates dial-on-demand applications.
When set to Block, all Type 20 packets are not propagated across the
WAN connection.
PPP Profile/Bridge
The Bridge menu contains the parameters needed for exchanging
bridged packets with the PPP peer.
Bridge/Mode
Write security: 3; Read security: 5
When set to On (def), the Router Option Module will attempt to negotiate PPP BCP with the PPP peer. Bridging can be used even in
route mode only if the PPP peer cannot support certain PPP protocols for that particular routing protocol. See Bridge/WAN IP Bridge
and Bridge/WAN IPX Bridge on page page 4-14 for further details.
PPP Profile/PPP
The Router Option Module supports the IETF standards for the
Point-to-Point Protocol. The PPP state machine running in the Router Option Module can be fine-tuned to support many applications
that can be employed. The configurable items under this menu can
be changed from their default values for special cases.
PPP/VJ Compression
Write security: 3; Read security: 5
When set to On, the Router Option Module will perform TCP/IP
header compression known as Van Jacobson compression to the
PPP peer. Normally, this is not necessary over ISDN connections.
Set to Off (def) to disable it.
