4 Configure MP-BGP, set up IBGP peer relation between PEs, and set up EBGP peer
relation between PEs and their CEs.

■ Enable the exchanging of label-carried IPv4 route between the following
routers: PE1 and ASBR-PE1, PE2 and ASBR-PE2, ASBR-PE1 and ASBR-PE2.
■ Make each ASBR-PE change the next hop to its own when it advertises routes
to the PE in the same AS.
■ Configure routing policy on each ASBR-PE as follows: make the ASBR-PE assign
MPLS label when it advertises a route received from the PE in this AS to the
ASBR-PE in the peer AS, and let the ASBR-PE assign a new MPLS label when it
advertises a label-carried IPv4 route to the PE in this AS.
