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:
