Update the routing table Update the routing table Topology change by - Router R2 sends updated routeGrid R3 selects the new post-route selection table Figure 6-1-1 RIP Topology ChangeThe topology of router R1 changes. Router R1 updates its own routing table. Router R1 sends the entire updated routing table to neighboring router R2. router R2 updates its own routing table. Router R2 sends the entire updated routing table to neighboring router R3.From the above update process, you can see that each router updates its local routing table before sending the updated routing table when it learns that the network topology has changed. Next, look at how the routers running the RIP protocol learn from each other. Before the RIP protocol is running, routers Rl, R2, and R3 in Figure 6-1-2Only the relevant directly connected routing information is available on1 10.1.0.0 10.2.0.0 10.3.0.0 Running the RIP routing protocol, routers Rl, R2, and R3 each announce their directly connected networks. 10.4.0.02 Assuming R1 sends a routing update first, R1 tells R2 about its directly connected networks 10.1.0.0 and 1020.0 with a 1-hop metric.3 After R2 receives the routing table from R1, R2 compares its own routing table with the routing table passed by R1, and R2 finds that its own routing tableR2 finds out that there is already 10.2.0.0 in its routing table, and it is still a directly connected route, the administrative distance of the directly connected route is 0, the administrative distance of the learned RIP route is 120, the directly connected route is better, R2 ignores the 1020.0 passed by R1.
