Type 5 external LSA remove

[JurajK]

Hi I've written bad IP address as I redistributed the loopback interfaces into OSPF.  I want to remove the IP address from ospf database but the command

 no network A.B.C.D  wildcard mask area X 

under the router ospf subinterface has no effect. I wanna point it out that bad IP address has no interface

R1(config)#route-map TST
R1(config-route-map)#match interface lo1 

R1(config)#router ospf 1
R1(config-router)#router-id 0.0.0.1

R1(config-router)#network 10.1.9.1 0.0.0.0 area 0
R1(config-router)#redistribute connected route-map TST subnets

R1(config-router)# no network 10.1.9.1 0.0.0.0 area 0 

Thanks for help

Hello @JurajK ,

>> I wanna point it out that bad IP address has no interface

so it should be already removed from OSPF database

check with

show ip ospf database external <prefix>

Hope to help

Can you more elaborate 

LO now which IP/mask it have ?

You can defualt address under LO then add IP again

The ospf will advertise the new IP

perfect. perhaps trivial but i couldn't find it before. I have used always the possibilities with "no ...." 

Thanks a lot
