Hello
The above command will tell you what routing process are active and what interfaces are assigned to them, however there is a more specific commend to show you this.

Yes.

Thanks Joseph. What does below lines means?
Vlan3808 is up, line protocol is down
02-03-2017 08:12 AM
May be Vlan 3808 is not in use ,to bring the line protocol up for vlan . we need to pass it on Trunks and active access ports.

BTW, older IOS versions don't support the brief option.

show ip ospf interface brief as Paul mentioned.
