configure isis priority

configure isis [vlan all | {vlan} vlan_name] priority priority {level[1 | 2]}

Description

This command sets the priority used for DIS election on broadcast interfaces.

Syntax Description

vlan all Applies the configuration to all IS-IS VLAN (Virtual LAN)s.
vlan_name Specifies a single VLAN to which the configuration applies.
priority priority Sets the priority value. The range is 0 to 127.
level [1 | 2] Limits the configuration to either level 1 or level 2. If neither level 1 nor level 2 is specified, the configuration applies to both levels.

Default

64.

Usage Guidelines

A higher priority value is preferred over a lower priority value. The priority is encoded in level 1 or level 2 hello PDUs. This command is not valid for point-to-point interfaces. Note that a priority of 0 has no special meaning other than the fact that it is the lowest priority. A router with a priority of 0 can still become the DIS.

Example

The following command configures priority level 32 for SJvlan:

configure isis SJvlan priority 32
