When the route is learned from R3. The Routing Descriptor Blocks show
"3.3.11.3 <http://3.3.11.3/>, from 3.3.3.3" <http://3.3.3.3/>. Shouldn't it
be something like 13.13.11.3, from 13.13.3.3?
Routing Descriptor Blocks:
* 3.3.11.3, from 3.3.3.3, 00:00:02 ago, via Serial2/0
Route metric is 20, traffic share count is 1
