RIP is a distance vector routing protocol, it used hop count as its only metric for path selection. Advertised routes with hop counts greater than 15 are unreachable. Messages are broadcast every 30 seconds.
To configure rip, the commands are;
- (config)# router rip
- (config-router)# network “networking address”
The three commands you can use to verify and troubleshoot a RIP config are;
- show ip route
- show ip protocols
- debug ip rip
The passive-interface command is used to stop RIP updates from being sent out an interface where RIP updates are not needed. For example, a lan interface would only need to send out RIP updates if there is another RIP enabled device on the lan.
RIP entries are displayed in the routing table with the source code of R and have an administrative distance of 120. Default routes are propagated in RIP by configuring a static default route and using the default-information-originate command in RIP.
RIP v1 does not support VLSM
