Configuring Local Ldp Session Parameters; Configuring Remote Ldp Session Parameters - H3C S5500-HI Series Mpls Configuration Manual

Configuring local LDP session parameters

LDP sessions established between local LDP peers are local LDP sessions. To establish a local LDP
session:
Determine the LDP transport addresses of the two peers and make sure that the LDP transport
•
addresses are reachable to each other. This step is to establish the TCP connection.
• If many LDP sessions exist between the two LSRs or the CPU is occupied much, you must adjust timers
to ensure the stability of the LDP sessions.
To configure local LDP session parameters:
Step
1. Enter system view.
2. Enter interface view.
3. Set the link Hello timer.
4. Set the link Keepalive timer.
5. Configure the LDP transport
address.

Configuring remote LDP session parameters

LDP sessions established between remote LDP peers are remote LDP sessions. Remote LDP sessions are
mainly used in Martini MPLS L2VPN and Martini VPLS. For more information about remote session
applications, see
If a local adjacency exists between two peers, no remote adjacency can be established between them.
If a remote adjacency exists between two peers, you can configure a local adjacency for them. However,
the local adjacency can be established only when the transport address and keepalive settings for the
local peer match those for the remote peer, in which case the remote adjacency will be 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.
To establish a remote LDP session, you must perform the following operations:
Determine the LDP transport addresses of the two peers and make sure that the LDP transport
•
addresses are reachable to each other. Do this to establish the TCP connection.
If many LDP sessions exist between the two LSRs or the CPU is occupied often, adjust timers to ensure
•
the stability of the LDP sessions.
