Configurations on PE 2 are similar to those on PE 1, and are thus omitted here.
After completing the configurations above, you can execute commands display mpls ldp session,
display bgp peer and display isis peer respectively on either PE 1 or PE 2. You should see that the
LDP session is established, the BGP peer relationship is established and in the Established state, and
the IS-IS neighbor relationship is established and up.
The following takes PE 1 for illustration.
