4. Configure the Link Hello
interval.
mpls ldp timer hello-interval
interval
By default, the Link Hello interval is
five 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.
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.
To configure parameters for LDP sessions:

3. Configure the Keepalive hold
time.
mpls ldp timer keepalive-hold
timeout
By default, the Keepalive hold time
is 45 seconds.
4. Configure the Keepalive
interval.
mpls ldp timer keepalive-interval
interval
By default, the Keepalive interval is
15 seconds.
5. Configure the LDP transport
address.
mpls ldp transport-address
{ ip-address | interface }
By default, the LDP transport
address is the LSR ID of the local
device if the interface where you
want to establish an LDP session
belongs to the public network. If
the interface belongs to a VPN, the
LDP transport address is the
primary IP address of the interface.
If the interface where you want to
establish an LDP session is bound
to a VPN instance, the interface
with the IP address specified with
this command must be bound to the
same VPN instance.
Configuring LDP backoff
If LDP session parameters (for example, the label advertisement mode) are incompatible, two LDP peers
cannot establish a session, and they will keep negotiating with each other.
