Usage Guidelines

A smaller value indicates a higher preference. To make RIPng routes take precedence over other IGP routes, set a smaller preference value for RIPng routes. The preference values also determine which routing protocol's routes are optimal routes in an IPv6 routing table.

Example

# Set the preference of RIPng routes to 120.

# Set the preference of the RIPng routes matching route-policy policy1 to 60.

<HUAWEI> system-view

[HUAWEI] ripng 100
