Reference Guide
To lter the routes for redistribution, combine route-maps and IP prex lists. If the route or packet matches the congured criteria, the
OS10 processes the route based on the permit or deny conguration of the prex list.
When a route-map and a prex list combine:
• For a route map with the permit action:
–
If a route matches a prex-list set to deny, the route is denied
– If a route matches a prex-list set to permit, the route is permitted and any set of actions are apply
• For a route map with the deny action:
– If a route matches a prex-list set to deny, the route is denied
– If a route matches a prex-list set to permit, the route is denied

Match routes
Congure 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 lters in a route-map low. The
set commands do not require a corresponding match command.
• Match routes with a specic metric value in ROUTE-MAP mode, 0 to 4294967295.

• Match routes whose next hop is a specic interface in ROUTE-MAP mode.
