Implementing OSPF
Command or Action
Example:
RP/0/RSP0/CPU0:router(config)# router ospf
1
or
RP/0/RSP0/CPU0:router(config)# router
ospfv3 1
Step 3
router-id { router-id }
Example:
RP/0/RSP0/CPU0:router(config-ospf)#
router-id 192.168.4.3
Step 4 area area-id
Example:
RP/0/RSP0/CPU0:router(config-ospf)# area
10
Step 5
Do one of the following:
• range ip-address mask [ advertise |
not-advertise ]
• 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
or
RP/0/RSP0/CPU0:router(config-ospf-ar)#
range 4004:f000::/32 advertise
Step 6
interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)#
interface GigabitEthernet 0/2/0/3
Step 7
commit
Purpose
Note
Configures a router ID for the OSPF process.
Note
Enters area configuration mode and configures a nonbackbone area
for the OSPF process.
• The area-id argument can be entered in dotted-decimal or IPv4
Consolidates and summarizes OSPF routes at an area boundary.
• The advertise keyword causes the software to advertise the
• The not-advertise keyword causes the software to suppress
• In the first example, all subnetworks for network 192.168.0.0
• In the second example, two or more IPv4 interfaces are covered
Enters interface configuration mode and associates one or more
interfaces to the area.
