Another question:
If Area 0 use md5 authentication, Area 6(only used in Virtual-link) use plain text authentication, how should I config under router ospf process which of these solution are accepted ?
router ospf 1000
area 0 authentication message-digest
area 6 virtual-link x.x.x.x authentication
Or
router ospf 1000
area 0 authentication message-digest
area 6 virtual-link x.x.x.x message-digest
Or
router ospf 1000
area 0 authentication message-digest
area 6 authentication
area 6 virtual-link x.x.x.x
Or
router ospf 1000
area 0 authentication message-digest
area 6 authentication
area 6 virtual-link x.x.x.x message-digest
