convergence. Whenever a router changes the metric of a route, it is required to send update messages almost immediately

4.1.1.5 RIP Command

version - To specify a RIP version used globally by the router (version 1 and 2)

auto-summary– enable automatic network number summarization.

Network – Enable routing on an IP network

Neighbor – specify a neighbor router

Bind-interface– Enable RIP protocol on some interface

Default-metric– set metric of redistributed routes

Distance – define an administrative distance

Distribute-list– Filter networks in routing updates

Offset-list–To add an offset to incoming and outgoing metrics to routes learned via RIP

Passive-interface- To disable sending routing updates on an interface.

Redistribute - To redistribute routes from one routing domain into another routing domain.

Timers – adjust routing timers

Validate-update-source- Perform sanity checks against source address of routing updates

Show ip route – show all routes learned through RIP

Debug ip rip - To show RIP operation information and update messages sent or received by routers.

The difference between RIPV1 and RIPV2 is RIPV2 is not a new protocol; rather it is RIPV1 with some extensions. The most of important extensions in RIPV2 is addition of a Subnet mask field to the routing update entries, enabling the use of VLSM.
