Manipulating administrative distance (AD) is another way to help with a mutual redistribution scenario.
You can use route tags in redistribution scenarios to filter and/or manipulate routes.
A route must appear in the routing table via an IGP in order for that routes to be able to be voted ‘best” by BGP.
For God’s sake, do not lower the AD of EIGRP! Havoc will ensue.
It’s simple as pie to enable MD5 auth to a BGP peer.

This is required blogging…and reading for that matter. A good chunk of this is taken from my CCNP posts from last year. Corrections, please.
Make my corrections! Please!
You can configure an EIGRP router to filter routes from being advertised or from being accepted.
