After you complete the above configurations, LDP sessions should be established between PE 1, P,
and PE 2. Issuing the display mpls ldp session command, you can see that the Session State field
has a value of Operational. Issuing the display mpls ldp lsp command, you can see that the LSPs
established by LDP. The following takes PE 1 as an example:
