RIP

6.1 Convergence

How does RIP react to changes in the topography?
In the following example of a line interruption between router B and router C,
you can see the resulting changes in the address table:
Assumptions:
The interruption occurs 5 seconds after B sent its routing table.
The routers send their routing table every 30 seconds (= factory setting).
There is an interval of 15 seconds between when router A sends its
routing table and when router B sends its routing table.
