RIP must receive regular routing updates to maintain a correct routing table. Response messages

containing a router's full routing table are transmitted every 30 seconds. If a router does not send an update

within a certain amount of time, the hop count to that route is changed to unreachable (a route hop metric

of 16 hops). Another timer sets the amount of time before the unreachable routes are removed from the

routing table.

This first RIP version does not support VLSM or CIDR and is not widely used.

RIPv2

RIPv2 adds support for subnet fields in the RIP routing updates, thus qualifying it as a classless routing

protocol. The RIPv2 message format includes entries for route tags, subnet masks, and next hop addresses.

Another enhancement included in RIPv2 is multicasting for route updates on IP multicast address

FTOS supports both versions of RIP and allows you to configure one version globally and the other

version or both versions on the interfaces. The C-Series and E-Series both support 1,000 RIP routes.

ECMP paths supported

By default, RIP is disabled in FTOS. To configure RIP, you must use commands in two modes: ROUTER

RIP and INTERFACE. Commands executed in the ROUTER RIP mode configure RIP globally, while

commands executed in the INTERFACE mode configure RIP features on that interface only.

RIP is best suited for small, homogeneous networks. All devices within the RIP network must be

configured to support RIP if they are to participate in the RIP.
