Changing the maximum LSP lifetime

The maximum LSP lifetime is the maximum number of seconds an un-refreshed LSP can remain in
the device’s LSP database. The maximum LSP lifetime can be from 1 – 65535 seconds. The
default is 1200 seconds (20 minutes).

To change the maximum LSP lifetime to 2400 seconds, enter a command such as the following.

BigIron RX(config-isis-router)# max-lsp-lifetime 2400

Syntax: [no] max-lsp-lifetime <secs>

The <secs> parameter specifies the maximum LSP lifetime and can be from 1 – 65535 seconds.
The default is 1200 seconds (20 minutes).

NOTE

The max-lsp-lifetime and the lsp-refresh-interval must be set in such a way that the LSPs are
refreshed before the max-lsp-lifetime expires; otherwise, the device's originated LSPs may be timed
out by it's neighbors. Refer to

“Changing the LSP refresh interval”

on page 956.

Changing the LSP refresh interval

The LSP refresh interval is the maximum number of seconds the device waits between sending
updated LSPs to its IS-IS neighbors. The interval can be from 1 – 65535 seconds. The default is
900 seconds.

To change the LSP refresh interval to 20000 seconds, enter a command such as the following.

BigIron RX(config-isis-router)# lsp-refresh-interval 20000

Syntax: [no] lsp-refresh-interval <secs>

The <secs> parameter specifies the maximum refresh interval and can be from 1 – 65535
seconds. The default is 900 seconds (15 minutes).

Changing the LSP generation interval

The LSP generation interval is the minimum number of seconds the device waits between sending
updated LSPs to its IS-IS neighbors. The interval can be from 1 – 120 seconds. The default is 10
seconds.

To change the LSP generation interval to 45 seconds, enter a command such as the following.

BigIron RX(config-isis-router)# lsp-gen-interval 45

Syntax: [no] lsp-gen-interval <secs>

The <secs> parameter specifies the minimum refresh interval and can be from 1 – 120 seconds.
The default is 10 seconds.

Changing the LSP interval and retransmit interval

You LSP interval is the rate of transmission, in milliseconds of the LSPs. The retransmit interval is
the time the device waits before it retransmits LSPs. To define an LSP interval, enter a command
such as the following.

BigIron RX(config-isis-router)# lsp-interval 45
