Configuring OSPF
6
The commands in this example configure some static IP routes, then configure a route map and
use the route map for redistributing static IP routes into OSPF.
The ip route commands configure the static IP routes. The route-map command begins
configuration of a route map called “abc”. The number indicates the route map entry (called the
“instance”) you are configuring. A route map can contain multiple entries. The software compares
packets to the route map entries in ascending numerical order and stops the comparison once a
match is found.
The match command in the route map matches on routes that have 5 for their metric value (cost).
The set command changes the metric in routes that match the route map to 8.
The redistribute static command enables redistribution of static IP routes into OSPF, and uses
route map “abc“ to control the routes that are redistributed. In this example, the route map allows a
static IP route to be redistributed into OSPF only if the route has a metric of 5, and changes the
metric to 8 before placing the route into the OSPF route table.
The following command shows the result of the redistribution filter. Since only one of the static IP
routes configured above matches the route map, only one route is redistributed. Notice that the
route’s metric is 5 before redistribution but is 8 after redistribution.
Syntax: [no] redistribution connected | static [route-map map-name]
The connected | static parameter specifies the route source.
The route-map map-name parameter specifies the route map name. The following match
parameters are valid for OSPF redistribution:
• match ip address | next-hop acl-num
• match metric num
• match tag tag-value
The following set parameters are valid for OSPF redistribution:
• set ip next hop ip-addr
• set metric [+ | - ]num | none
• set metric-type type-1 | type-2
• set tag tag-value
NOTE
You must configure the route map before you configure a redistribution filter that uses the route
map.
NOTE
When you use a route map for route redistribution, the software disregards the permit or deny action
of the route map.
