The Express 6100/612 0 provides the following basic functions:
1. LAN Bridge: Bridging provides a point-to-point connection
between two LANs. The bridge learning function scans the
source and destination media access control (MAC) addresses of
all packets on its local LAN and determines which packets
should be transmitted over the IDSL link. Applications include
connectivity between single user or small offices to corporate
LANs.
2. IP Router: T he Express 6100/6120 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.
3. IPX Router: IPX routers and services can be exchanged between
the Express 6100/6120 and other devices using RIP and Service
Advertising Protocol (SAP). Watchdog serialization filtering and
spoofing can permit the ISDN to be idle during no application
traffic periods.
4. Network Address Translation (NAT):Single networks can con-
nect to the Internet with this function. The Express 6100/6120
translates outgoing IP packets over the IDSL to the IP router at
the Internet Service Provider. Many popular Internet applications are supported.

5. PPP or Frame Relay: The layer two 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 Express 6100/
6120
The Express 6100/6120 is a Router and Transparent Learning Bridge.
Its features can be easily configured and used once several basic concepts are understood.
Factory Default
The Express 6100/6120 comes from the factory configured for MAC
Bridging 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 two configuration is Auto Detect, which automatically detects PPP or Frame Relay.
Bridging
In Bridge Mode, the Express 6100/6120 can be used to connect two
LAN segments. In this mode, all protocols are supported because they
are transported across the IDSL link at the MAC layer. The Spanning
Tree Algorithm can be used to guarantee a loop-free topology. MAC
addresses are “learned” by each Express 6100/6120 to prevent nonWAN packets from being bridged.
IP Routing
The Express 6100/6120 operates as an IP router when the Configuration/IP/IP Router/Mode option is configuredto On.InPPPmode,the
Express 6100/6120 uses an IP unnumbered WAN interface; the IP address and mask assigned to the unit’s LAN interface 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 de-

fault gateway (recommended for remote applications when there are
no other routers on the remote LAN).
IPX Routing
Network routes and services are learned and advertised using Novell’s RIP and SAP.
Concurrent Routing And Bridging
The Express 6100/6120 can route IP and IPX as well as bridge non-IP/
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 accept a protocol,
theExpress6100/6120willfallback to any combinationof routingand
bridging.
Network Address Translation Mode
NAT is a special mode of operation in which the Express 6100/6120
obtains a dynamically assigned IP address from the peer router (typically an Internet Service Provider). This allows a network of computers to appear as a single IP address.
NAT is enabled if the layer-two protocol is PPP and the PPP profile
has the IP parameter NATset to Yes, orthe layer two protocolis Frame
Relay and a D LCI mapping has the IP Map/Nat parameter set t o Yes.
The network computer’s IP stack may use DHCP to request an IP address, default gateway address, and domain name server addresses
from the Express 6100/6120.

Rear Panel
The Express 6100/6120 has one RJ-45 jack, labeled ISDN, on the rear
panel for network connection (see Figure 1-9 on page 1-9 and Figure
1-10 on page 1-9).
The OFF/ON switch block is for factory default and firmware down-
loading. With switch 1 in the up or OFF position, the Express 6100/
6120 will immediately go into a download mode when power is enabled. Switch 1 must be in the down or ON position in order to boot
up normally. Switch 2 in the up or OFF position will force the entire
configuration to be factory defaulted.
