Configuring Link Hello timers

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enter the view of the interface
where you want to establish

an LDP session.

interface interface-type
interface-number

N/A

3.

Configure the Link Hello hold

time.

mpls ldp timer hello-hold timeout

By default, the Link Hello hold time
is 15 seconds.

4.

Configure the Link Hello

interval.

mpls ldp timer hello-interval
interval

By default, the Link Hello interval is
five seconds.

Configuring Targeted Hello timers for an LDP peer

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Enter LDP view.

mpls ldp

N/A

3.

Specify an LDP peer and enter

LDP peer view. The device will
send unsolicited Targeted

Hellos to the peer and can

respond to the Targeted Hellos
sent from the peer.

targeted-peer peer-lsr-id

By default, the device does not
send Targeted Hellos to or
receive Targeted Hellos from

any peer.

4.

Configure the Targeted Hello
hold time.

mpls ldp timer hello-hold timeout

By default, the Targeted Hello

hold time is 45 seconds.

5.

Configure the Target Hello
interval.

mpls ldp timer hello-interval

interval

By default, the Targeted Hello
interval is 15 seconds.

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.

Configuring LDP sessions parameters for Basic Discovery mechanism

To configure parameters for LDP sessions to be established using Basic Discovery mechanism:
