==== Description
6+
7+
Verifies basic RIP functionality by configuring two routers (R1 and R2)
8+
with RIP on their interconnecting link. The test ensures RIP routes are
9+
exchanged between the routers and end-to-end connectivity is achieved.
10+
11+
The test PC uses data1 interface to connect to R1's data port, and data2
12+
interface to connect to R2's data port (which does not have RIP enabled).
13+
This verifies that RIP status information remains accessible when a router
14+
has non-RIP interfaces.
15+

==== Topology
17+
18+
image::topology.svg[RIP Basic topology, align=center, scaledwidth=75%]
19+
20+
==== Sequence
21+
22+
. Set up topology and attach to target DUTs
23+
. Configure targets
24+
. Wait for RIP routes to be exchanged
25+
. Test connectivity from PC:data1 to R2 loopback via RIP
26+
. Test connectivity from PC:data2 to R1 loopback via RIP
