retransmit 5 seconds, trans-delay 1 second, and the dead 40 seconds.
4.2.19 Configuring the OSPF Area to Support Packet Authentication
All the routers in one area must use the same authentication mode (no authentication,
simple text authentication or MD5 cipher text authentication). If the mode of supporting
authentication is configured, all routers on the same segment must use the same
authentication key. To configure a simple text authentication key, use the ospf
authentication-mode simple command. And, use the ospf authentication-mode
md5 command to configure the MD5 cipher text authentication key if the area is
configured to support MD5 cipher text authentication mode.
Perform the following configuration in OSPF Area view.
Table 4-19 Configuring the OSPF Area to Support Packet Authentication
Operation Command

authentication type
authentication-mode { simple |
md5 }
Cancel the configured authentication
undo authentication-mode
By default, the area does not support packet authentication.
4.2.20 Configuring OSPF Packet Authentication
