The FTOS implementation of route maps allows route maps with no match command or no set command.
When there is no match command, all traffic matches the route map and the set command applies.
Important Points to Remember
• For route-maps with more than one match clause:
• Two or more match clauses within the same route-map sequence have the same match commands
(though the values are different), matching a packet against these clauses is a logical OR operation.
• Two or more match clauses within the same route-map sequence have different match commands,
matching a packet against these clauses is a logical AND operation.
• If no match is found in a route-map sequence, the process moves to the next route-map sequence until
a match is found, or there are no more sequences.
• When a match is found, the packet is forwarded; no more route-map sequences are processed.
• If a continue clause is included in the route-map sequence, the next or a specified route-map
sequence is processed after a match is found.
Configuration Task List for Route Maps
You configure route maps in the ROUTE-MAP mode and apply them in various commands in the
ROUTER RIP and ROUTER OSPF modes.
The following list includes the configuration tasks for route maps:
• Create a route map (mandatory)
• Configure route map filters (optional)
• Configure a route map for route redistribution (optional)
• Configure a route map for route tagging (optional)
Create a route map
Route maps, ACLs, and prefix lists are similar in composition because all three contain filters, but route
map filters are do not contain the permit and deny actions found in ACLs and prefix lists. Route map filters
match certain routes and set or specify values.
To create a route map and enter the ROUTE-MAP mode, use the following command in the
CONFIGURATION mode:
Command Syntax Command Mode Purpose
route-map map-name [permit | deny]
[
sequence-number]
CONFIGURATION Create a route map and assign it a unique name.
The optional permit and deny keywords are the
action of the route map. The default is permit.
The optional parameter seq allows you to assign
a sequence number to the route map instance.
