Cisco 7204 I have for example 5 subinterfaces Gigabit Ethrnet 0/0.100 (dotq1 vlan100) with ospf Gigabit Ethrnet 0/0.101 (dotq1 vlan101) with ospf Gigabit Ethrnet 0/0.102 (dotq1 vlan102) with ospf Gigabit Ethrnet 0/0.103 (dotq1 vlan100) without ospf Gigabit Ethrnet 0/0.104 (dotq1 vlan100) without ospf
serial 0/0 with ospf
when I remove interface Gigabit Ethernet GigabitEthernet 0/0.103 all ospf neighbour on interface 100,101,102 down i see only ospf neighbour on serial
Interface gigabit is still up and protocol is up I still have access from interace 104 to router (up)
Maybe soft bug 12.3(6b) ?
