Step 9 exit
Example:
RP/0/RP0/CPU0:router(config-ospf-ar)# exit
Step 10 area area-id
Example:
RP/0/RP0/CPU0:router(config-ospf)# area 1
Step 11 authentication [ message-digest | null ]
Example:
RP/0/RP0/CPU0:router(config-ospf-ar)#
authentication
Step 12 interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-ospf-ar)# interface
GigabitEthernet 0/1/0/0
Step 13 Repeat Step 12 for each interface that must communicate,
using the same authentication.
Step 14
interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-ospf-ar)# interface
GigabitEthernet 0/3/0/0
Step 15
authentication [ message-digest | null ]
Example:
RP/0/RP0/CPU0:router(config-ospf-ar-if)#
authentication null

Purpose
Enters area OSPF configuration mode.
Enters area configuration mode and configures a
nonbackbone area 1 for the OSPF process.
• The area-id argument can be entered in
dotted-decimal or IPv4 address notation, such as area
1000 or area 0.0.3.232. However, you must choose
one form or the other for an area. We recommend
using the IPv4 address notation.
Enables Type 1 (plain text) authentication that provides
no security.
• The example specifies plain text authentication (by
not specifying a keyword). Use the
authentication-key command in interface
configuration mode to specify the plain text password.
Enters interface configuration mode and associates one or
more interfaces to the nonbackbone area 1 specified in
Step 7.
• All interfaces configured inherit the authentication
parameter values configured for area 1.
—
Enters interface configuration mode and associates one or
more interfaces to a different authentication type.
Specifies no authentication on GigabitEthernet interface
0/3/0/0, overriding the plain text authentication specified
for area 1.
• By default, all of the interfaces configured in the same
area inherit the same authentication parameter values
of the area.
