When running multiple OSPF processes, the
passive-interface is not respected per process and is applied globally. So the following config is invalid:
router ospf 1 passive-interface GigabitEthernet0/0 passive-interface GigabitEthernet0/1 network 172.16.0.0 0.0.0.255 area 0 network 192.168.10.0 0.0.0.255 area 0 router ospf 10 passive-interface GigabitEthernet0/0 network 10.0.0.0 0.0.0.255 area 51 network 192.168.10.0 0.0.0.255 area 51
The only way is to remove passive interfaces on interfaces that will broadcast any OSPF process.
