1
00:00:00.100 --> 00:00:07.600
Two Cisco routers share a transit link, with a loopback at each end.

2
00:00:16.000 --> 00:00:23.450
Start EIGRP with the same autonomous system number on both routers.

3
00:00:25.250 --> 00:00:33.250
The neighbor table shows router two, and the topology table shows the learned loopback.

4
00:00:35.250 --> 00:00:42.750
Check the installed EIGRP route, then ping from one loopback to the other.

5
00:00:46.850 --> 00:00:53.350
Make the transit interface passive and watch the learned route disappear.

6
00:00:58.450 --> 00:01:05.450
Remove the passive setting and confirm that the route and ping return.

7
00:01:23.750 --> 00:01:31.200
Remove EIGRP from both routers and confirm the remote route is gone.

8
00:01:52.950 --> 00:02:00.950
Enable RIP version two on both routers and include the transit and loopback networks.

9
00:02:16.900 --> 00:02:24.900
The remote loopback is now a one hop RIP route, and the ping succeeds.

10
00:02:42.450 --> 00:02:49.000
Remove router two’s loopback network from RIP to withdraw its advertisement.

11
00:02:51.050 --> 00:02:58.050
The remote loopback stops replying, but the directly connected router still answers.

12
00:03:15.600 --> 00:03:22.600
Advertise the loopback again and verify that the route and ping return.
