Firewall and OSPF - Passive interfaces??

Unanswered Question

I have a pair of ASA5550 with OSPF enabled on the outside interfaces with our internet routers. Firewalls get the candidate default route from the internet routers.

Anyway, when I do a "sh ospf interface" all interfaces are listed under should be only the outside interface.

Is there a passive interface command just like for routers??

Under your router ospf configuration what have you used as the "network x.x.x.x area 0"

ie. does x.x.x.x also cover you other interfaces ?
