Routing Information Protocol
[edit | edit source]Overview of RIP
[edit | edit source]Routing Information Protocol is a distance vector routing protocol. It transfers the complete routing table to all interfaces periodically and only uses hop count to determine the best path to a remote network.
Configuring RIP
[edit | edit source]RIP is relatively simple to configure. The following is an example of how to configure RIP on a router.
Enter router configuration mode.
router#conf t
Turn on the RIP protocol
router(config)#router rip
Assign which networks RIP will advertise (this also has the effect of selecting which interfaces RIP will be active on)
router(config)#network x.x.x.x
When using the network x.x.x.x expression x.x.x.x will be the subnet to advertise. As RIP is a classful routing protocol this will need to take the form of a standard Class A,B, or C address e.g. 10.0.0.0, 172.16.0.0 or 192.168.1.0.
Example
[edit | edit source]Configure RIP to advertise the subnets 192.168.1.0 and 192.168.5.0
router#conf t
router(config)#router rip
router(config)#network 192.168.1.0
router(config)#network 192.168.5.0
To turn off RIP
router#conf t
router(config)#no router rip
