NOTE:

The configurations for PE 2 are similar to those for PE 1.

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 a BGP peer relationship has been established and has reached the Established

set up. Take PE 1 as an example:
