Configuration
Prerequisites

Configuration Procedure

To do...
Enter system view
Enable LDP capability for a VPN
instance and enter MPLS LDP VPN
instance view
Configure the LSR ID for the VPN
instance
c
CAUTION:
For LDP-enabled interfaces, configurations in MPLS LDP VPN instance view
■
affect only interfaces bound to VPN instances, while configurations in MPLS
LDP view do not affect any interfaces bound to VPN instances. When
configuring the transport address of an LDP instance, you must use the IP
address of the interface bound to the VPN instance.
By default, LDP adjacencies on the private network are established using
■
addresses of the LDP-enabled interfaces, while those on the public network are
established using the LDP LSR ID.
Before configuring LDP GR, be sure to complete this task:
Configuring MPLS LDP capability on the devices to be the GR restarter or GR
■
helper
Complete the following configurations on a GR restarter. A GR helper requires no
additional configuration.
n
A single device can act as both GR restarter and GR helper at the same time.
Follow these steps to configure LDP GR:
