Default

The RIP router can listen and supply a default route, usually represented as 0.0.0.0 in the rout- ing table. When a router does not have an explicit route to a destination network in its routing table, it uses the default route to forward those packets.

Metric

The metric field contains a configurable value between 1 and 15 (inclusive) which specifies the current metric for the interface. The metric value typically indicates the total number of hops to the destination. The metric value of 16 represents an unreachable destination.

Authentication

RIPv2 authentication uses plaintext password for authentication. If configured using Authenti- cation password, then it is necessary to enter an authentication key value.

The following method is used to authenticate a RIP message:

„If the router is not configured to authenticate RIPv2 messages, then RIPv1 and unauthenti- cated RIPv2 messages are accepted; authenticated RIPv2 messages are discarded.

„If the router is configured to authenticate RIPv2 messages, then RIPv1 messages and RIPv2 messages which pass authentication testing are accepted; unauthenticated and failed authentication RIPv2 messages are discarded.

For maximum security, RIPv1 messages are ignored when authentication is enabled

(cfg/l3/rip/if x/auth/password); otherwise, the routing information from authen- ticated messages is propagated by RIPv1 routers in an unauthenticated manner.

RIP Configuration Example

NOTE – An interface RIP disabled uses all the default values of the RIP, no matter how the RIP parameters are configured for that interface. RIP sends out RIP regular updates to include an UP interface, but not a DOWN interface.
