i am in the process of preparing my JNCIA certification so i decided to create few labs to practice all topics.
in this lab im trying to test a route policy that should not import an external OSPF route, the external route is injected by a CISCO IOS router coming from EIGRP:
access-list 1 permit 18.104.22.168 0.0.0.0
route-map EIGRP 10
match ip address 1
set metric 50
set metric-type type-2
router ospf 10
redistribute eigrp 10 subnets route-map EIGRP
when i run show ospf database external on VMX routers i can still see the external route as shown here even though i have a policy that should be blocing this external route:
i can still see this injected external router on other VMX router's RIB . so what am i doing wrong here ?
The important part is:
OSPF import policy allows you to prevent external routes from being added to the routing tables of OSPF neighbors. The import policy does not impact the OSPF database. This means that the import policy has no impact on the link-state advertisements. The filtering is done only on external routes in OSPF. The intra-area and interarea routes are not considered for filtering. The default action is to accept the route when the route does not match the policy.
Your example is showing Ospf DB - so this is correct - you need to check the RIB (show route) to ensure it's working properly

thanks for the clarification, indeed the route does no longer exist in the local RIB.
