isis retransmit-interval

Use this command to configure the minimum interval between retransmissions of the same LSP.

Syntax

isis retransmit-interval interval
no isis retransmit-interval interval

Parameters

interval Specifies the minimum interval between retransmissions of the same LSP in seconds. Valid values are 1 - 300. The default value is 5.

Defaults

None.

Mode

Interface configuration.

Usage

The retransmit interval should be greater than the expected round-trip delay between any two routers on the attached network. Retransmissions occur when LSPs are dropped. Higher retransmission values have little effect on reconvergence. The more neighbors routers have, and the more paths over which LSPs can be flooded, the higher this value can be made.

The “no” form of this command resets the retransmit interval to the default value of 5 seconds.

Example

This example shows how to configure the retransmit interval to 10 seconds for VLAN 100:

System(rw)->configure
System(rw-config)->interface vlan 100
System(rw-config-intf-vlan.0.100)->isis retransmit-interval 10
System(rw-config-intf-vlan.0.100)->
