Cisco routers: configuring RIP
Routing Information Protocol (RIP) is an Interior gateway protocol that uses the distance-vector routing algorithm. The original specification of RIP, defined in RFC 1058, uses classful routing. The periodic routing updates do not carry subnet information, lacking support for variable length subnet masks (VLSM). RIPv2 introduces VLSM support, multicast and authentication capabilities. Although RIP has important limitations (slow convergence times, 15 hop limit, full routing updates periodically…) it’s very easy to configure and can come in handy for some networks. To configure RIP in your cisco router you should follow these steps:
router> enable router# configure terminal router(config)#router rip router(config-router)#network 192.168.2.0 router(config-router)#network 192.168.3.0 router(config-router)#network 192.168.4.0 router(config-router)#version 2
You have to specify all the interfaces in which you want to run RIP with network commands. And that’s all. You have RIP running on your router. Note: In most current networking environments, RIP is not the preferred choice for routing as its capabilities are poor compared to EIGRP, OSPF, or IS-IS.
