R21xx-HP FlexFabric 11900 Layer 3 IP Routing Command Reference
185
Usage guidelines
If a routing policy is specified in this command, the preference set by the routing policy applies to the
matching routes. Other routes use the preference set by the preference command.
If multiple routing protocols find routes to the same destination, the route found by the routing protocol
with the highest preference is selected as the optimal route.
Examples
# Configure the preference for IS-IS as 25.
<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] preference 25
priority
Use priority to assign convergence priorities to specific IS-IS routes.
Use undo priority to remove the configuration.
Syntax
priority { critical | high | medium } { prefix-list prefix-list-name | tag tag-value }
undo priority { critical | high | medium } [ prefix-list | tag ]
Default
IS-IS routes have the lowest convergence priority.
Views
IS-IS view
Predefined user roles
network-admin
Parameters
critical: Specifies the highest convergence priority.
high: Specifies the high convergence priority.
medium: Specifies the medium convergence priority.
prefix-list prefix-list-name: Specifies an IP 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.
IS-IS host routes have a medium convergence priority.
Examples
# Assign the high convergence priority to IS-IS routes permitted by IP prefix list standtest.
<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] priority high prefix-list standtest
