lsp-buf-size

Use this command to configure the LSP buffer size based upon the specified maximum size of LSPs originated by this IS-IS routing instance.

Syntax

lsp-buf-size size [level-1 | level-1-2 | level-2]

no lsp-buf-size size

Parameters

`size`	Specifies the maximum allowed size of LSPs originated by this IS-IS routing instance. Valid values are 500 - 16000 bytes. The default value is 1492.
level-1	(Optional) Specifies that the configured maximum LSP size is restricted to level 1.
level-1-2	(Optional) Specifies that the configured maximum LSP size is for both level 1 and level 2. (Default).
level-2	(Optional) Specifies that the configured maximum LSP size is restricted to level 2.

Defaults

If no level option is specified, this configuration applies to both level 1 and level 2 routers.

Mode

IS-IS router configuration.

Usage

Using LSP sizes greater than 1492 bytes requires that the size of the IS-IS database be increased. This command increases the size of the IS-IS database to account for larger LSP sizes. The “no” form of this command resets the maximum size of LSPs that originate from this IS-IS instance to the default value of 1492.

Example

This example shows how to configure the maximum size of LSPs that originate from this IS-IS instance to 1600:

System(rw)->configure
System(rw-config)->router isis
System(rw-config-isis)->lsp-buf-size 1600
System(rw-config-isis)->
