Configuration procedure
1 Configure IGP on the MPLS backbone
This example uses OSPF. The detailed configuration steps are omitted.
After configuration, issuing the display ip routing-table command on each LSR,
you should see that it has learned the routes to the LSR IDs of the other LSRs.
Issuing the display ospf peer command, you should see that OSPF adjacencies
have been established and reached the state of Full.
2 Configure MPLS basic capability and LDP to establish LDP LSPs
The detailed configuration steps are omitted.
After configuration, you can issue the display mpls ldp session and display
mpls ldp peer commands to view the LDP sessions and peer relationship
established, or the display mpls lsp command to view the LSPs established.
3 Configure BGP L2VPN capability
# Configure PE 1.
