7.3 Route Redistribution
7.3.9
Verifying redistribution operation
Following is the best way to verify redistribution operation:
  • Know your network topology, particularly where redundant routes exist.
  • Display the routing table of the appropriate routing protocol on a variety of routers in the internetwork using the show command. For example, check the routing table on the ASBR as well as some of the internal routers in each AS.
  • Perform a traceroute on some of the routes that go across the ASs to verify that the shortest path is being used for routing. Make sure that you run traces especially to networks for which redundant routes exist.
  • If you do encounter routing problems, use traceroute and debug commands to observe the routing update traffic on the ASBRs and internal routers.
