Cisco ASR 9000 Series Configuration Guide

PurposeCommand or Action
Enables Type 1 (plain text) authentication that provides
no security.
authentication [ message-digest | null ]
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)# authentication
Step 11
•
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.
interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)# interface
GigabitEthernet 0/1/0/0
Step 12
•
All interfaces configured inherit the authentication
parameter values configured for area 1.
—
Repeat Step 12 for each interface that must communicate, using
the same authentication.
Step 13
Enters interface configuration mode and associates one
or more interfaces to a different authentication type.
interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)# interface
GigabitEthernet 0/3/0/0
Step 14
Specifies no authentication on GigabitEthernet interface
0/3/0/0, overriding the plain text authentication
specified for area 1.
authentication [ message-digest | null ]
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar-if)#
authentication null
Step 15
•
By default, all of the interfaces configured in the
same area inherit the same authentication
parameter values of the area.

Step 16
Controlling the Frequency That the 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.
