Route map is a route policy. It can use prefix-list, access-lists, as-path, large community list etc. to create an effective route policy. A route-map consists of series of statements that check if a route matches the policy to permit or deny a route. Also, set criteria can be used to alter the properties of route as they are installed in the routing table.
XCO 3.2.0 supports match and set criteria for large community list and IPv6 prefix list.
For supported commands on route map match and set, see ExtremeCloud Orchestrator Command Reference, 3.6.0 .
