4) Configure MP-BGP, set up IBGP peer relation between PEs, and set up EBGP
peer relation between PEs and their CEs.
Note:
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.
Up to 100 LSPs with two layer labels can be created for the public network.
