Configuration procedure
1. Configure MPLS L3VPN on the provider carrier backbone: start IS-IS as the IGP, enable LDP on PE
1 and PE 2, and establish an MP-IBGP peer relationship between the PEs.
# Configure PE 1.

NOTE:
The configurations for PE 2 are similar to those for PE 1. (Details not shown)
After completing the configurations, issue the display mpls ldp session command on PE 1 or PE 2;
the output shows that the LDP session has been established successfully. Issue the display bgp peer
command; the output shows that the BGP peer relationship has been established and has reached
the Established state. Issue the display isis peer command; the output shows that an IS-IS neighbor
relationship has been set up. Take PE 1 as an example:
[PE1] display mpls ldp session
