[c-nsp] ospf authentication

[Paul Stewart]

Hi there...
I need to bring up OSPF authentication network wide and just wanted to confirm something....
If I go around to each interface on each router and add a "ip ospf message-digest-key 1 md5 kal" therefore setting up a password using MD5 etc.  It's not until I add "area 0 authentication message-digest" into our "router ospf 1" section that this actually takes effect right?
Because a number of these routers are remote, you can understand that I need to be careful bringing up authentication..;)
interface Loopback0
  ip address 70.70.70.70 255.255.255.255
 !
 interface Serial2
  ip address 192.16.64.2 255.255.255.0
  ip ospf message-digest-key 1 md5 kal
 !
 router ospf 10
  network 192.16.64.0 0.0.0.255 area 0
  network 70.0.0.0 0.255.255.255 area 0
 area 0 authentication message-digest
