I need some help with BGP. When reading the labs, I never get a clear
feeling for what the ultimate goal of configuring BGP is. When configuring
IGPs the goal is to have connectivity from every subnet to every subnet.
With BGP this isn't always the case.
When I read the lab I have no problems deciding who should be neighbors
(that is usually explicitly stated) and what kind of relationship to make
(e/ibgp, confederation, route-reflector). Once I have that going and some
entries in the bgp tables I start to think about synchronization and
redistribution and then get all glossy eyed and pass out. I freeze up and
don't know what direction I am going.
After considerable thought about what my problem is I only can guess that
the goal of BGP is to provide connectivity from every AS to every AS, and
this doesn't mean that I can get to every subnet in every AS, just the
subnets that are part of BGP.
Does anyone have any guidance on this? I am lost and by the time I get to
the more advanced topics in BGP I am totally out of focus and don't
understand why I am doing what I am doing.
TIA
