Cisco Systems 3560 Manual De Usuario

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 non-updating 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 pseudonetwork 
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.
