RIPng basic functions

[Interoperability Test Scenario]

Last Update: February 26, 2000

This scenario verifies interoperability when the target ROUTER is attached to the model network.

Subjects:
Routers exchange Routing Information each other with RIPng. Check if routers determine the best route.
Verification Points:

Exchange of Routing Information from RIPng between routers, and packets are forwarded to the best route.
If a path is broken, the ROUTER transmits Routing Information Update and packets are forwarded to another route.
If the ROUTER's cost of route is increased, the ROUTER transmits Routing Information Update and packets are forwarded to the best route.
