Configuring Ldp Gr - 3Com S7906E Configuration Manual

LDP instances have different LDP LSR IDs if the address spaces overlap. Otherwise, the TCP
connections cannot be established normally.
Follow these steps to configure LDP instances:
To do...
Enter system view
Enable LDP capability for a
VPN instance and enter MPLS
LDP VPN instance view
Configure the LDP LSR ID for
the VPN instance
Configurations in MPLS LDP VPN instance view affect only LDP-enabled interfaces bound to the
VPN instances, while configurations in MPLS LDP view do not affect interfaces bound to VPN
instances. When configuring the transport address of an LDP instance, you need to use the IP
address of the interface bound to the VPN instance.
By default, LDP adjacencies on a private network are established using addresses of the
LDP-enabled interfaces, while those on the public network are established using the LDP LSR ID.
