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-

61200176L1-1 Express 6100/6120 User Manual 1-5

Chapter 1. Understanding IDSL and the Express 6100/6120

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.

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.

Security

Securityon network devices is a major concern foralmost anyone with a network. The Express 6100/6120 provides many tools for securing the local network from hostile users. Connections can be authenticated using passwords. A RADIUS client can also be used.

The Telnet and web browser configuration can also be protected using the same authentication methods. Each menu item in the Express 6100/6120 has a security level associated with it. A Telnet session is assigneda privilege levelwhich determines which menu items are accessible to the Telnet client. See Security Levels on page 3-7 for more information on menu security levels.

Filters can be defined to prevent certain addresses or protocols from being transferred from LAN-to-WAN, WAN-to-LAN, or WAN-toWAN.

As already mentioned, a web browser can be used to configure the Express 6100/6120. This is accomplished by entering http://10.0.0.1 on anyWindowsInternetExplorer browser. If theExpress 6100/6120’sIP address has been changed from the factory default, then 10.0.0.1 should be replaced by that address.

»» IP/Proxy ARP

Write security: 4; Read security: 5

This feature allows the network portion of a group of addresses to be shared among several physical network segments. The ARP protocol itselfprovides a way fordevices 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. 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 Express 6100/6120 will answer the request with its own hardware ad-

The PPP peer can be authenticated using three standard methods: PAP (Password Authentication Protocol), CHAP (Challenge Handshake Protocol) and EAP (Extensible Authentication Protocol). The strengthof the authentication is determinedin the order EAP, CHAP, followed by 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 readableformat. Caremust be takennot to 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:

» Configuration/Frame Relay

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: Permanent Virtual Circuits (PVC) and Switched Virtual Circuit (SVC). 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 andtear down is done by a carriervia a network management system. SVCs require setup and tear down and are generally not available fromFrame Relay carriers. Virtually all FrameRelay communications is done using PVCs. The Express 6100/6120 supports PVCs only.

Anumber calledthe Data Link Connection Identifier (DLCI) 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) This is an ANSI standard and is the most com-

monly used standard in the US.

Annex A This is the CCITT European standard. LMI This was developed by a vendor consortium

and is also known as the “consortium” management interface specification. It is still used by some carriers in the U.S.

This parameter is the interval that the Express 6100/6120 polls the Frame Relay switch using the maintenance protocol selected above.

The value is in seconds and ranges from 5 to 30 seconds with a default of 1 5 seconds.

»» Frame Relay/DLCI Mapping

This menu allows each DLCI to be mapped to a particular Frame Relay maintenance protocol. Each protocol parameter can be individually configured for each DLCI. By factory default, the DLCI map is empty.

When empty and a maintenanceprotocol other than static is used, the Express 6100/6120 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 connections are made using bridge group 1.

When more than one DLCI mapping is listed, the Express 6100/6120 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, it looksfor an entry that has 0 in the DLCI field. This entryis considered the default entry to use when no match occurs. If this default entry is not present, the Express 6100/6120 falls back to using IARP (as discussed in the previous paragraph) to determine the protocols to use with that particular virtual circuit. If a static maintenance protocol is used, at least one DLCI mapping must be specified.

IP/NAT

Write security: 3; Read security: 5

The Express 6100/6120 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 3-15 for more global options. Setting this option to On will cause the Express 6100/6120 to perform NAT. In the Off (def) position, the unit will route across the connection normally.

IP/Route

The IP parameters are configured in this menu. UsuallytheExpress 6100/6120 will automatically discover the PPP peer’s networks using PPP IPCP and/or RIP.

IPX/Type 20 Packets

Write security: 3; Read security: 5

For c ert ain protocol implementations, like NetBIOS, to function in the NetWare environment, routes must allow a broadcast packet to be propagated throughout the IPX networks. The Type 20 IPX packet is used specifically for this purpose. This causes special handling of this packet by the Express 6100/6120. When a router receives this type o f 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 1Mbps (like ISDN). However, when set to Pass (def),theExpress 6100/6120 will allowthesepackets 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.
