• 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.
Step 12 interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-ospf-ar)# interface TenGigE 0/1/0/0
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.
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 TenGigE 0/3/0/0
Enters interface configuration mode and associates one or more interfaces to a different authentication type.
Step 15 authentication [ message-digest | null ]
Example:
RP/0/RP0/CPU0:router(config-ospf-ar-if)# authentication null
Specifies no authentication on TenGigE 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.

Control Frequency That Same LSA Is Originated or Accepted
for OSPF
This task explains how to tune the convergence time of OSPF routes in the routing table when many LSAs
need to be flooded in a very short time interval.
SUMMARY STEPS
1. configure
2. Do one of the following:
• router ospf process-name
• router ospfv3 process-name
3. router-id { router-id }
