Controlling The Frequency That The Same Lsa Is Originated Or Accepted For Ospf - Cisco ASR 9000 Series Routing Configuration Manual

Controlling the Frequency That the Same LSA Is Originated or Accepted for OSPF

Command or Action
Step 11
authentication [ message-digest | null ]
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)# authentication
Step 12 interface type interface-path-id
Example:
RP/0/RSP0/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/RSP0/CPU0:router(config-ospf-ar)# interface
GigabitEthernet 0/3/0/0
Step 15 authentication [ message-digest | null ]
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar-if)#
authentication null

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.

Purpose
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.
