Cisco ASR 9000 Series Routing Configuration Guide

PurposeCommand or Action
Example:
RP/0/RSP0/CPU0:router(config)# router ospf
1
The process-name argument is any alphanumeric string no
longer than 40 characters.
Note
or
RP/0/RSP0/CPU0:router(config)# router
ospfv3 1
Configures a router ID for the OSPF process.
router-id { router-id }
Step 3
Example:
RP/0/RSP0/CPU0:router(config-ospf)#
router-id 192.168.4.3
We recommend using a stable IPv4 address as the router
ID.
Note
Enters area configuration mode and configures a nonbackbone area
for the OSPF process.
area area-id
Example:
RP/0/RSP0/CPU0:router(config-ospf)# area
Step 4
•
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.

Consolidates and summarizes OSPF routes at an area boundary.Do one of the following:
Step 5
•
range ip-address mask [ advertise |
not-advertise ]
•
The advertise keyword causes the software to advertise the
address range of subnetworks in a Type 3 summary LSA.
•
The not-advertise keyword causes the software to suppress
the Type 3 summary LSA, and the subnetworks in the range
remain hidden from other areas.
•
range ipv6-prefix / prefix-length [
advertise | not-advertise ]
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)#
range 192.168.0.0 255.255.0.0 advertise
•
In the first example, all subnetworks for network 192.168.0.0
are summarized and advertised by the ABR into areas outside
the backbone.
•
In the second example, two or more IPv4 interfaces are covered
by a 192.x.x network.
or
RP/0/RSP0/CPU0:router(config-ospf-ar)#
range 4004:f000::/32 advertise
Enters interface configuration mode and associates one or more
interfaces to the area.
interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)#
interface GigabitEthernet 0/2/0/3
