prefix-priority

Use prefix-priority to assign a convergence priority to the specified IPv6 IS-IS routes.

Use undo prefix-priority to remove the configuration.

Syntax

prefix-priority { critical | high | medium } { prefix-list prefix-list-name | tag tag-value }

prefix-priority route-policy route-policy-name

undo prefix-priority { critical | high | medium } [ prefix-list | tag ]

undo prefix-priority route-policy

Default

IPv6 IS-IS routes have the low convergence priority.

Parameters

critical: Specifies the highest convergence priority.

high: Specifies the high convergence priority.

medium: Specifies the medium convergence priority.

route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters.

prefix-list prefix-list-name: Specifies an IPv6 prefix list by its name, a case-sensitive string of 1 to 63 characters.

tag tag-value: Specifies a tag value in the range of 1 to 4294967295.

Usage guidelines

The higher the convergence priority, the faster the convergence speed.

IPv6 IS-IS host routes have a medium convergence priority.

Examples

# Assign the high convergence priority to IS-IS routes permitted by IPv6 prefix list standtest.
