• 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 and 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
Configure route maps in ROUTE-MAP mode and apply the maps in various commands in ROUTER RIP and
ROUTER OSPF modes.
The following list includes the configuration tasks for route maps, as described in the following sections.
• 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)
Creating a Route Map
Route maps, ACLs, and prefix lists are similar in composition because all three contain filters, but route map
filters do not contain the permit and deny actions found in ACLs and prefix lists.
Route map filters match certain routes and set or specific values.
To create a route map, use the following command.
• Create a route map and assign it a unique name. The optional
permit
and
deny
keywords are the actions
of the route map.
CONFIGURATION mode
route-map map-name [permit | deny] [ sequence-number ]
The default is permit .
The optional
seq
keyword allows you to assign a sequence number to the route map instance.
Configured Route Map Examples
The default action is permit and the default sequence number starts at 10 . When you use the keyword
deny
in configuring a route map, routes that meet the match filters are not redistributed.
To view the configuration, use the
show config
command in ROUTE-MAP mode.
Dell(config-route-map)#show config
!
route-map dilling permit 10
Dell(config-route-map)#
You can create multiple instances of this route map by using the
sequence number
option to place the
route maps in the correct order. Dell Networking OS processes the route maps with the lowest sequence
number first. When a configured route map is applied to a command, such as
redistribute
, traffic passes
