Following is the best
way to verify redistribution operation:
- Know your network
topology, particularly where redundant routes exist.
- Show 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 trace
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 trace and
debug
commands to observe the routing update traffic on the ASBRs and
internal routers.
Note: Running
debug requires extra processing by the router, so if the
router is already overloaded, initiating debug is not
recommended.
