To do...
Specify the LDP remote peer
IP address
Set the targeted Hello timer
Set the targeted Keepalive
timer
Configure the transport
address
In the current implementation, LDP itself does no send any label information
through remote sessions, and remote sessions are used only to transfer messages
for L2VPNs. For applications of remote sessions, refer to
MPLS L2VPN" on page
CAUTION:
If Hello adjacency exists between two peers, no remote adjacency can be
■
established between them. If remote adjacency exists between two peers, and
local adjacency is then created for the remote peer, the remote adjacency is
removed. That is, only one remote session or local session can exist between
two LSRs, and the local session takes precedence over the remote session.
The remote peer IP address to be configured must be different from all existing
■
remote peer IP addresses. Otherwise, the configuration fails.
You can specify the routes that are allowed to trigger the establishment of LSPs:
All static and IGP routes.
■
IGP routes that can survive the IGP route filtering based on an IP address prefix
■
list.
An IP address prefix list affects only static routes and IGP routes.
Follow these steps to configure the policy for triggering LSP establishment:
To do...
Enter system view
Enter MPLS view
Configure the LSP
establishment
triggering policy
For an LSP to be established, an exactly matched routing entry must exist on
■
the LSR. With loopback addresses using 32-bit masks, only exactly matched
host routing entries can trigger LDP to establish LSPs.
For information about IP address prefix list, refer to

on page 993.
