Hello Naveen,

     I tried it locally with both 7.0 and 7.2. I can see that it is working fine. When router ospf is disabled configuration under interface goes away too. Is this your configuration or did you have more configuration under interface?

Thanks

Subject: Interface mode ospf config not getting deleted opon unconfiguring ospf router

Hi,

     In FRR 7.2 OSPF, When ospf router is Unconfigured, interface mode ospf configurations are not getting deleted from running config.

     Is this behavior designed with any specific reason  ?

Example:

  router ospf

    ospf rouer-id 1.1.1.1

 interface Ethernet8

    ip ospf area 0

   With above config, if I issue command “no router ospf”,   interface level ospf configs will not get removed/deleted.

Regards

Naveen
