Updating routing table
First, experience shows that triggered updates can cause excessive load on networks with limited capacity or networks with many routers on them.
A system that implements dynamic routing relies on routing protocols, such as RIP for IPv4 networks, and RIPng for IPv6 networks, to maintain its routing tables.
A system that runs only static routing does not rely on a routing protocol for routing information and for updating the routing table.
Instead, you must maintain the system's known routes manually through the command.
I wasn't sure if RIP sends all its routing table to its neighbors or just sends downed route with metric of 16.
After a triggered update is sent, a timer should be set for a random interval between 1 and 5 seconds.
