Enter system view system-view —
Create a remote peer entity and
enter MPLS LDP remote peer view mpls ldp remote-peer
remote-peer-name
Required
Configure the remote peer IP
address
remote-ip ip-address Required
Configure LDP to advertise
prefix-based labels through a
remote session
prefix-label advertise
Optional
By default, LDP does not advertise
prefix-based labels through a
remote session.
Set the targeted Hello timer mpls ldp timer hello-hold value
Optional
45 seconds by default
Set the targeted Keepalive timer
mpls ldp timer keepalive-hold
value Optional
45 seconds by default
Configure the LDP transport
address mpls ldp transport-address
ip-address Optional
MPLS LSR ID of the LSR by default
NOTE:
•
The IP address specified as the LDP transport address must be the IP address of an interface on the
device.
• The remote peer IP address to be configured must be different from all existing remote peer IP addresses.
• 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 and those for the remote peer match, respectively, in which case the remote adjacency is
removed. Only one remote session or local session can exist between two LSRs, and the local session
takes precedence over the remote session.
• By default, LDP does not advertise any prefix-based label mapping message through a remote session,
and remote sessions are used only to transfer messages for L2VPNs. For more information about remote
session applications, see the Martini MPLS L2VPN configuration in the chapter “MPLS L2VPN
configuration.”
