I am building a site with 4 routers connecting sprerate BGP AS areas connected by 2 switches as the core. Where is the best place to do the redistribution? I am currentlly do this at the core but am thinking this might be wrong. If I am suppose to do the redistribution at the router level do I use a metric per remote AS to prioritize? And do I do that at every router or peer all the routers and distribute from one router?
I have this problem too.
