3.9.6 Establishing the MP-EBGP Peer Relationship Between PEs
By introducing extended community attributes to BGP, MP-IBGP can advertise VPNv4 routes
between PEs. PEs of different ASs are generally not directly connected. Therefore, to set up the
EBGP connection between the PEs of different ASs, configure the permitted maximum hops
between the PEs.
