Peers need to be IP reachable to establish a BGP session.

Route reflectors can reduce the number of iBGP sessions required.

iBGP peers have to be adjacent to each other.

The multihop parameter needs to be configured when eBGP peers are not adjacent to each other.

LOCAL_PREFERENCE is set to 100.
