Dear all,
Would like to ask about a decent way, methodology or Cisco document to trace
problems that results after redistribution (route feedback, routing loops
and sub optimal routing) on a single or multiple routers for more multiple
routing protocols.
In other words, how to verify during the lab. that your redistribution
didn't create sub-optimal or routing loops in your topology.
Thanks for your help,
Karim.
