Hellos to the peer and can
respond to the Targeted Hellos
received from the peer.

By default, the device does not
send Targeted Hellos to any
peers, or respond to Targeted
Hellos received from any peers.

Configuring LDP session parameters
This task configures the following LDP session parameters:
•
Keepalive hold time and Keepalive interval.
•
LDP transport address—IP address for establishing TCP connections.
LDP uses Basic Discovery and Extended Discovery mechanisms to discovery LDP peers and
establish LDP sessions with them.
When you configure LDP session parameters, follow these guidelines:
•
The configured LDP transport address must be the IP address of an up interface on the device.
Otherwise, no LDP session can be established.
•
Make sure the LDP transport addresses of the local and peer LSRs can reach each other.
Otherwise, no TCP connection can be established.
