PurposeCommand or Action
RP/0/RP0/CPU0:router(config-ospf-ar)#
dead-interval 40
(Optional) Specifies the interval between hello packets
that OSPF sends on the interface.
hello-interval seconds
Example:
Step 7
It is recommended to set the hello timer interval
to the default of 10 seconds. OSPF sessions may
flap during switchover if hello-interval timer
configured is less then default value.
Note
RP/0/RP0/CPU0:router(config-ospf-ar)#
hello-interval 10
Enters interface configuration mode and associates one or
more interfaces for the area configured in Step 4.
interface type interface-path-id
Example:
Step 8
• In this example, the interface inherits the
nonbroadcast network type and the hello and dead
RP/0/RP0/CPU0:router(config-ospf-ar)# interface
GigabitEthernet 0/2/0/0
intervals from the areas because the values are not
set at the interface level.
Configures the IPv4 address of OSPF neighbors
interconnecting to nonbroadcast networks.
Do one of the following:
Step 9
• neighbor ip-address [ priority number ] [
poll-interval seconds ][ cost number ]
or
• neighbor ipv6-link-local-address [ priority number
] [ poll-interval seconds ][ cost number ] [
database-filter [ all ]]
Configures the link-local IPv6 address of OSPFv3
neighbors.
• The ipv6-link-local-address argument must be in
the form documented in RFC 2373 in which the
Example:
address is specified in hexadecimal using 16-bit
values between colons.
RP/0/RP0/CPU0:router(config-ospf-ar-if)# neighbor
10.20.20.1 priority 3 poll-interval 15
• The priority keyword notifies the router that this
neighbor is eligible to become a DR or BDR. The
or
RP/0/RP0/CPU0:router(config-ospf-ar-if)# neighbor
fe80::3203:a0ff:fe9d:f3fe
priority value should match the actual priority setting
on the neighbor router. The neighbor priority default
value is zero. This keyword does not apply to
point-to-multipoint interfaces.
• The poll-interval keyword does not apply to
point-to-multipoint interfaces. RFC 1247 recommends
that this value be much larger than the hello interval.
The default is 120 seconds (2 minutes).
• Neighbors with no specific cost configured assumes
the cost of the interface, based on the cost command.
On point-to-multipoint interfaces, cost number is
the only keyword and argument combination that
works. The cost keyword does not apply to NBMA
networks.
• The database-filter keyword filters outgoing LSAs
to an OSPF neighbor. If you specify the all keyword,
