Configuring OSPF
25
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. 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 bgp | connected | [rip] | [isis level-1| level-1-2| level-2] | [static
[route-map <map-name> ]
The bgp | connected | rip | isis | 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 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.
NOTE
For an external route that is redistributed into OSPF through a route map, the metric value of the
route remains the same unless the metric is set by a set metric command inside the route map. The
default-metric
<num> command has no effect on the route. This behavior is different from a route
that is redistributed without using a route map. For a route redistributed without using a route map,
the metric is set by the default-metric
<num> command.
Disable or re-enable load sharing
The device can load share among up to eight equal-cost IP routes to a destination. By default, IP
load sharing is enabled. The default is 4 equal-cost paths but you can specify from 2 – 8 paths.
