To create route map instances, use these commands. There is no limit to the number of set commands per route map, but
the convention is to keep the number of set filters in a route map low. Set commands do not require a corresponding match
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.
Route redistribution occurs when Dell EMC Networking OS 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 redistribute 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.
In the following example, the redistribute 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 interface 1/1/1 and that have
a metric of 255 are redistributed into the OSPF backbone area.
NOTE:
When re-distributing routes using route-maps, you must create the route-map defined in the redistribute
command under the routing protocol. If you do not create a route-map, NO routes are redistributed.
