Once this configuration is implemented, the routes identified by the ip prefix-list command and matched in the route map will have their
OSPFv2 administrative distance set to 200. This is displayed in the output from the show ip route command, as shown below.

Routes 1 and 2 demonstrate the actions of the example configuration as both display an OSPFv2 administrative distance value of 200.
Note that the value is applied to both OSPFv2 learned routes that match the route-map instance containing the set distance clause. The
other OSPFv2 route (route 3), which does not match the relevant instance, continues to have the default OSPFv2 administrative distance
of 110.
OSPFv2 route redistribution
Route redistribution imports and translates different protocol routes into a specified protocol type. On the device, redistribution is
supported for static routes, OSPF, RIP, and BGP. OSPF redistribution supports the import of static, RIP, and BGP routes into OSPF
routes.
NOTE
The device advertises the default route into OSPF even if redistribution is not enabled, and even if the default route is learned
through an IBGP neighbor. IBGP routes (including the default route) are not redistributed into OSPF by OSPF redistribution (for
example, by the OSPF
redistribute command).
In the figure below, the device acting as the ASBR (Autonomous System Boundary Router) can be configured between the RIP domain
and the OSPF domain to redistribute routes between the two domains.
NOTE
The ASBR must be running both RIP and OSPF protocols to support this activity.
NOTE
Do not enable redistribution until you have configured the redistribution route map. Otherwise, you might accidentally overload
the network with routes you did not intend to redistribute.
