Sets the keepalive time interval at which the session keepalive message is sent when no other LDP protocol message is sent to the LDP peer.
The default is six seconds.
Specifies the keepalive time interval in seconds. Enter an integer from 1 throughk 65535.
MPLS LDP configuration mode
The ka-interval and the ka-timeout configurations are mutually exclusive and you may have only one configured at a time. You must explicitly remove the configuration for one in order to change to the other configuration.
When the keepalive timeout value is configured, the show mpls ldp command displays keepalive interval as keepalive timeout divided by the keepalive interval count (ka-timeout/ka-in-count).
"Please clear LDP sessions for the new KA parameter value to take effect on existing sessions"
Use the no form of the command to reset the default of six seconds.
MPLS is supported only on devices based on the DNX chipset family. For a list of such devices, see "Supported Hardware".
The following example configures a keepalive interval of 10 seconds.
device# configure terminal device(config)# router mpls device(config-router-mpls)# ldp device(config-router-mpls-ldp)# ka-interval 10
