The configurations for PE 2 are similar to those for PE 1. The detailed configuration
steps are omitted.
After completing the above configurations, you should see that the LDP session
has been established successfully by issuing the display mpls ldp session
command on PE 1 or PE 2. Issuing the display bgp peer command, you should
see that the BGP peer relationship has been established and has reached the state
of Established. Issuing the display isis peer command, you should see that the
IS-IS neighbor relationship has been set up. Take PE 1 as an example:
