IP Access Control Lists (ACL), Prefix Lists, and Route-maps

Use these commands to create route map instances. There is no limit to the number of set and match 
commands per route map, but the convention is to keep the number of match and set filters in a route map 
low. 

 commands do not require a corresponding 

 command.

Configure a route map for route redistribution

Route maps on their own cannot affect traffic and must be included in different commands to affect routing 
traffic. To apply a route map to traffic on the E-Series, you must call or include that route map in a 
command such as the 

 or 

 commands in OSPF, ISIS, and BGP.

Route redistribution occurs when FTOS learns the advertising routes from static or directly connected 
routes or another routing protocol. Different protocols assign different values to redistributed routes to 
identify either the routes and their origins. The metric value is the most common attribute that is changed 
to properly redistribute other routes into a routing protocol. Other attributes that can be changed include 
the metric type (for example, external and internal route types in OSPF) and route tag. Use the 

 

command in OSPF, RIP, ISIS, and BGP to set some of these attributes for routes that are redistributed into 
those protocols. 

Route maps add to that redistribution capability by allowing you to match specific routes and set or change 
more attributes when redistributing those routes. 

 command calls the route map static ospf to redistribute only certain 

static routes into OSPF. According to the route map static ospf, only routes that have a next hop of 
Gigabitethernet interface 0/0 and that have a metric of 255 will be redistributed into the OSPF backbone 
area.

 

CONFIG-ROUTE-MAP

Assign an IPv6 address as the route’s next hop.

}

CONFIG-ROUTE-MAP

Assign an ORIGIN attribute.

 

CONFIG-ROUTE-MAP

Specify a tag for the redistributed routes.

 

CONFIG-ROUTE-MAP

Specify a value as the route’s weight.

Note: When re-distributing routes using route-maps, the user must take care to create the 
route-map defined in the 

 command under the routing protocol. If no route-map is 

created, then NO routes are redistributed.
