Introduction The TXPORT MultiPro series products can be optioned to be IP routers with the
addition of the LAN interface card. The model 9101 comes standard with the
router option while models 9000, 9111, and 9211 have an option that can be
ordered.
With the addition of the routing capabilities, MultiPro series products can fully
integrate LAN traffic with the legacy traffic residing on your network. The IP
router can handle small office networks as well as larger environments.
The router option allows flexibility in network design. The router can be used for a
leased line application as well as in standard frame relay networks.

RIP Summary
Description IP RIP is an Internal Gateway Protocol (IGP) that is based on distance vector
routing. IP RIP is the foundation upon which IPX RIP was built, therefore each
uses the same processes for discovering, maintaining, and prioritizing routes. RIP
sends route requests for obtaining routing information and send periodic route
updates for Routing Table synchronization. For route maintenance, IP RIPs are
sent each 30 seconds. RIP uses the Split Horizon Algorithm to maintain routes and
minimize convergence problem.
