Setting the LDP Hello Interval and Hold Timeout values
2
Setting the LDP Hello Interval globally for targeted LDP sessions
To modify the hello message interval for targeted LDP sessions to 20 seconds, enter the
hello-interval target command.
Brocade(config-mpls)# ldp
Brocade(config-mpls-ldp)# hello-interval target 20
Syntax: [no] hello-interval target seconds
The seconds variable specifies the value in seconds of the hello interval that the user is globally
configuring for LDP Targeted messages. The LDP hello interval can be from 1 – 32767 seconds.
When the user sets a new LDP hello interval, it takes effect immediately. The default value for LDP
Targeted Hello messages is 15 seconds.
The [no] option removes a previously configured LDP Targeted Hello Interval.
NOTE
This value can only be set globally for all Targeted LDP sessions on the router. Per-interface
configuration is only available for Link LDP sessions.
Setting the LDP Hello Interval per-Interface (link Only)
The user can set the LDP Hello Interval on a per-Interface basis. This option is only available for
Link LDP sessions. The following example configures the MPLS Interface at Ethernet port 1/1 with
a hello-interval of 10 seconds.
Brocade(config)# mpls
Brocade(config-mpls)# mpls-interface ethernet 1/1
Brocade(config-mpls-if-e100-1/1)# ldp-params
Brocade(config-mpls-if-e100-1/1-ldp-params)# hello interval 10
Syntax: [no] hello-interval seconds
The seconds variable specifies the value in seconds of the Hello Interval that the user is
configuring on this MPLS interface for LDP Link Hello messages.
No default value exists for this parameter. When a value is set here, it overrides any LDP Hello
Interval that was globally configured. However, when no value is set for this parameter, it defaults
either to the LDP Hello Interval that was configured globally or, when no value was configured
globally, to the default global value. For information about the global configuration, refer to
“Setting
the LDP Hello Interval globally for link LDP sessions” .
The [no] option removes a previously configured LDP Hello Interval.
Setting the LDP hold time sent to adjacent LSRs
The LDP hold time specifies how long the device waits for its LDP peers to send a Hello message.
When the device does not receive a Hello message within this time, the LDP session with the peer
can be terminated. The device includes the hold time in the Hello messages it sends out to its LDP
peers.
