530BConfiguring the routing policy
A routing policy on an ASBR performs the following operations:
• Assigns MPLS labels to routes received from the PEs in the same AS before advertising them
to the peer ASBR.
• Assigns new MPLS labels to the labeled routes to be advertised to the PEs in the same AS.
The configuration is the same as that in the Inter-AS IPv4 VPN option C solution. For more
information, see "
843HConfiguring inter-AS option C."
