Redistribute routes
Add routes from other routing instances or protocols to the OSPFv2 process and include BGP, static, or connected routes in the
OSPFv2 process. Do not route IBGP routes to OSPFv2 unless there are route-maps associated with the OSPFv2 redistribution.
When you configure the system to redistribute BGP routes to OSPF, by default, the system redistributes only the external BGP
(eBGP) routes. Use the [no] bgp redistribute-internal command under BGP to allow or block the redistribution of
IPv4 or IPv6 internal BGP ((iBGP) routes to OSPF in a default or nondefault VRF instance. To know more information, see
Redistribute iBGP route to OSPF.
NOTE:
With the redistribute static command in the running configuration, if a static route is configured which is
also learned through OSPF, the static route is installed in the routing table even if the static route preference is higher than
OSPF.
● Enter the routes that redistribute into the OSPFv2 process in ROUTER-OSPF mode.
redistribute {bgp as-number| connected | static} [route-map map-name]
○ bgp | connected | static—Enter a keyword to redistribute those routes.
○ route-map map-name—Enter the name of a configured route map.
Configure redistribute routes
OS10(conf-router-ospf-10)# redistribute bgp 4 route-map aloha
OS10(conf-router-ospf-10)# redistribute connected route-map aloha
OS10(conf-router-ospf-10)# redistribute static route-map aloha
Before Release 10.5.2.0, the redistribute command redistributed active and inactive route paths. By default, from Release
10.5.2.0 and beyond, this command redistributes only active route paths. If you have configured route redistribution, when you
upgrade to Release 10.5.2.0, the inactive route paths are no longer redistributed.
To redistribute both active and inactive routes, you must configure a route map with the inactive-path-additive rule and
apply the route map to the redistribute command.
Consider a case where two route paths, one learned from the OSPF peer and the other leaked from another VRF, having the
same metric and cost are present. In this case, the routing table prioritizes the local route over the leaked route. If you have
