3Com 3031 Command Reference Manual page 563

Description
Using the authentication-mode command, you can configure one area of OSPF to
support the authentication attribute. Using the undo authentication-mode
command, you can cancel the authentication attribute of this area.
By default, an area does not support authentication attribute.
All the routers in one area must use the same authentication mode (no
authentication, supporting 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.
For the related command, see ospf authentication-mode.
Example
Enter area 0 view.
[3Com-ospf-1] area 0
Specify the OSPF area 0 to support MD5 cipher text authentication.
[3Com-ospf-1-area-0.0.0.0] authentication-mode md5

Parameter
md5: MD5 cipher text authentication mode.
process-id: OSPF process number. If no process number is specified, all the
process debugging is enabled or disabled.
event: Enables OSPF event information debugging.
packet: Enables OSPF packet information debugging. There are five sorts of
packets in OSPF as follows:
ack: LSAck packet.
dd: Database Description packet.
hello: Hello message.
request: Link State Request packet.
update: Link State Update packet.
Lsa-generate: Enables OSPF LSA packet information debugging.
spf: Enables the debugging of the calculation of the OSPF shortest-path tree.
te: Enables the debugging of OSPF TE.
