To make sure that the PE router endpoints have discovered each other, enter the show mpls ldp
•
discovery command. When an PE router receives an LDP Hello message from another PE router, it
considers that router and the specified label space to be "discovered."
Router# show mpls ldp discovery
To make sure that the label distribution session has been established, enter the show mpls ldp
•
neighbor command. The third line of the output shows that the state of the LDP session is
operational and shows that messages are being sent and received.
Router# show mpls ldp neighbor

To ensure that the label forwarding table is built correctly, enter the show mpls forwarding-table
command to verify that a label has been learned for the remote PE and that the label is going from
the correct interface to the correct next-hop.
