Layer 3 Routing Commands 1518
Syntax
route-map map-tag [permit | deny] [sequence-number]
no route-map map-tag [permit | deny] [sequence-number]
• map-tag — Text name of the route map. Route maps with the same name
are grouped together in order of their sequence numbers. A route map
name may be up to 32 characters long and comprised of any printable
character except a question mark. Enclose the map-tag in quotes to
embed blanks in the name.
• permit — (Optional) Permit routes that match all of the match
conditions in the route map.
• deny — (Optional) Deny routes that match all of the match conditions in
the route map. Packets matching deny routes use the routing table.
• sequence-number — (Optional) An integer used to order the set of route
maps. Route maps are ordered from lowest to greatest sequence number,
with lower sequence numbers being considered first. If no sequence
number is specified, the system assigns a value ten greater than the last
statement in the route map. The range is 0 to 65,535.
Default Configuration
No route maps are configured by default. If no permit or deny tag is specified,
permit is the default.

User Guidelines
Apply an ACL rule on the VLAN interface to perform policy based routing
based on the VLAN ID as a matching criteria for incoming packets. Packets
matching a deny rule or a deny route-map are routed using the routing table.
There is no implicit deny all at the end of a route map. Packets not matching
any clause are routed using the routing table.
Route maps with no set clause are ignored. One use of a route map is to limit
the redistribution of routes to a specified range of route prefixes. The
redistribution command specifies a route map which refers to a prefix list.
