API Guide

To filter the routes for redistribution, combine route-maps and IP prefix lists. If the route or packet matches the configured
criteria, OS10 processes the route based on the permit or deny configuration of the prefix list.
When a route-map and a prefix list combine:
● For a route map with the permit action:
○ If a route matches a prefix-list set to deny, the route is denied
○ If a route matches a prefix-list set to permit, the route is permitted and any set of actions apply
● For a route map with the deny action:
○ If a route matches a prefix-list set to deny, the route is denied
○ If a route matches a prefix-list set to permit, the route is permitted and any set of actions apply

Match routes
Configure match criterion for a route-map. There is no limit to the number of match commands per route map, but keep the
number of match filters in a route-map low. The set commands do not require a corresponding match command.
● Match routes with a specific metric value in ROUTE-MAP mode, from 0 to 4294967295.
