    Chapter 1: Understanding ISDN and the Express L128/L128T IP Router: The Express L128/L128T 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 ta- ble.

  • Page 30: Bridging

    During a two B-channel PPP Multilink call, the Express L128T automatically drops one B-channel and provides it to the POTS port when a telephone call is placed or answered. When a POTS telephone call terminates, the Express L128 redials the second B-channel and supplies the bandwidth back to the LAN connection.

    Chapter 1: Understanding ISDN and the Express L128/L128T IP Routing The Express L128/L128T operates as a dial-up IP router when the Configura- tion/IP/IP Router/Mode option is configured to On. The Express L128/L128T 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.

  • Page 32: Ipx Routing

    PPP IP (IPCP) or IPX (IPXCP) protocols by allowing routing packets over the WAN connection using PPP Bridging (BCP). To perform this, the Express L128/L128T uses a “virtual” Ethernet port. This port is set up under the Con- figuration/Bridge menu.

    IPX networks. The Type 20 IPX packet is used specifically for this purpose. This causes special handling of this packet by the Express L128/ L128T. 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.

  • Page 89: Connection List/Bridge

    Bridge/Mode Write security: 3; Read security: 5 When set to On (def), the Express L128/L128T 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 pro- tocol.
