Parameters

route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters, to set a priority for the specified route prefixes.

Usage guidelines

Prefix prioritization enables the device to install prefixes in descending priority order: critical, high, medium, and low. The prefix priorities are assigned through routing policies. When a route is assigned multiple prefix priorities, it uses the highest priority.

By default, the 32-bit OSPF host routes have a medium priority and other routes have a low priority.

Examples

# Use a routing policy to assign the medium priority to the specified route prefixes.

[Sysname] ip prefix-list test index 10 permit 100.1.1.0 24
[Sysname] route-policy pre permit node 10
[Sysname-route-policy-pre-10] if-match ip address prefix-list test
[Sysname-route-policy-pre-10] apply prefix-priority medium
[Sysname-route-policy-pre-10] quit
