45 Routing Information Protocol c e s Routing Information Protocol is supported only on platforms: RIP is supported on the S-Series following the release of FTOS version 7.8.1.0, and on the C-Series with FTOS versions 7.6.1.0 and after. RIP is supported on the E-Series ExaScale platform with FTOS 8.1.1.0 and later. Routing Information Protocol (RIP) is based on a distance-vector algorithm, it tracks distances or hop counts to nearby routers when establishing network connections. • Protocol Overview • Implementation Information • Configuration Information • RIP Configuration Example RIP protocol standards are listed in the Appendix 64, Standards Compliance chapter. Protocol Overview RIP is the oldest interior gateway protocol. There are two versions of RIP: RIP version 1 (RIPv1) and RIP version 2 (RIPv2). These versions are documented in RFCs 1058 and 2453. RIPv1 RIPv1 learns where nodes in a network are located by automatically constructing a routing data table. The routing table is established after RIP sends out one or more broadcast signals to all adjacent nodes in a network. Hop counts of these signals are tracked and entered into the routing table, which defines where nodes in the network are located. The information that is used to update the routing table is sent as either a request or response message. In RIPv1, automatic updates to the routing table are performed as either one-time requests or periodic responses (every 30 seconds). RIP transports its responses or requests by means of UDP over port 520. Routing Information Protocol | 821
