Configuring Rip - Cisco ONS 15454 SDH Configuration Manual

Chapter 11 Configuring Networking Protocols
Using RIP, the switch sends routing information updates (advertisements) every 30 seconds. If a router
does not receive an update from another router for 180 seconds or more, it marks the routes served by
that router as unusable. If there is still no update after 240 seconds, the router removes all routing table
entries for the nonupdating router.
RIP uses hop counts to rate the value of different routes. The hop count is the number of routers that can
be traversed in a route. A directly connected network has a hop count of zero; a network with a hop count
of 16 is unreachable. This small range (0 to 15) makes RIP unsuitable for large networks.
If the router has a default network path, RIP advertises a route that links the router to the pseudo network
0.0.0.0. The 0.0.0.0 network does not exist; it is treated by RIP as a network to implement the default
routing feature. The switch advertises the default network if a default was learned by RIP or if the router
has a gateway of last resort and RIP is configured with a default metric. RIP sends updates to the
interfaces in specified networks. If an interface's network is not specified, it is not advertised in any
RIP update.
