set metric {+ | - | metric-value}
• Specify an OSPF or ISIS type for redistributed routes.

• Assign an IP address as the route’s next hop.
CONFIG-ROUTE-MAP mode
set next-hop ip-address
• Assign an IPv6 address as the route’s next hop.
CONFIG-ROUTE-MAP mode

• Assign an ORIGIN attribute.
CONFIG-ROUTE-MAP mode
set origin {egp | igp | incomplete}
• Specify a tag for the redistributed routes.

set tag tag-value
• Specify a value as the route’s weight.
CONFIG-ROUTE-MAP mode
set weight value
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 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 Tengigabitethernet interface 1/1 and that have a metric of 255 are redistributed
into the OSPF backbone area.
