Wow...making sense now! One more question... So an IBGP session as stated in the book, is made by use of the neighbor command. Either, you have your directly connected neighbors defined in each router or, you have the use of route reflectors? The only way you can defined a neighbor that is more than one hop (router) away is by using the multihop command? Is this true?
You can tell I have never seen BGP in a production environment (BGP is drastically different than what I am used to being, OSPF).
