Conﬁguring gated

Conﬁguring the RIP Protocol

B, D, and E pass routing information among themselves and update their

routes accordingly. C listens to the RIP conversation among B, D, and E,

and updates its routes accordingly. If routers D and E can both provide a

path to a network, but the path through router D is shorter, nodes B, C,

and E will use router D when routing packets to that network. If D goes

down, E becomes the new router to that network for nodes B, C, and E.

A: Cluster Node (or Isolated Node)

There is no need to run gated at this node since it is on a LAN with only

one router. Set a static default route to the cluster server (B) in the
