I am studying routing protocols for one of the certification exam, and confused with the following question:

  1. Does RIP V2 (Distance Vector protocol) store the distance vector table for every possible destination(networks) within a given AS. Here I mean like any given router on the AS knows all the network hops required to reach the destination computer/server, something like what 'trace route' command gives.

or

  1. only stores what its neighbour routers know?. Here I mean like any give router on the AS has only a partial answer to reach the destination computer/server.

Any help to throw light on this is appreciated.

RIP is an Interior Gateway Protocol, it means that it was designed to operate within a single autonomous system (AS).

RIP version 2 was developed as a fix of deficiencies on RIPv1 mainly in the ability of supporting CIDR.

To maintain backward compatibility, the original hop count limit of 15 remained, it means that if a router receives a RIP message indicating a subnet 16 hops farther, that information will be dismissed and the consequence will be that the routing table in that router won't show every destination available.

Being a distance vector protocol means it only learns and advertises prefixes with it's direct neighbors. It has no "full" view of the network topology.
