OSPF has the ability to redistribute routes of other routing protocols in the routing table into OSPF. In OSPF terminology, routes from other routing protocols are known as external routes and they are can be redistributed into OSPF as Type-5 LSAs.

If we wish to redistribute external routes through OSPF, we can configure the set protocols ospf redistribute command. And then configure a route map to control which type or specific prefixes are allowed to be redistributed through OSPF. The configuration shown below permits the redistribution of prefix 2.2.2.3/32 through OSPF.

admin@router2# set routing prefix-list IPv4 list2 permit prefix 2.2.2.3/32
admin@router2# set routing route-map map2 order 1 matching-policy "permit"
admin@router2# set routing route-map map2 order 1 match ip address prefix-list "list2"
admin@router2# set protocols ospf redistribute connected route-map "map2" |
