"""RIP Basic
|
|
|
|
Verifies basic RIP functionality by configuring two routers (R1 and R2)
|
|
with RIP on their interconnecting link. The test ensures RIP routes are
|
|
exchanged between the routers and end-to-end connectivity is achieved.
|
|
|
|
The test PC uses data1 interface to connect to R1's data port, and data2
|
|
interface to connect to R2's data port (which does not have RIP enabled).
|
|
This verifies that RIP status information remains accessible when a router
|
|
has non-RIP interfaces.
