Cisco NCS 5500 Series

DETAILED STEPS
Step 1 configure
Step 2 router ospf process-name
Example:
RP/0/RP0/CPU0:router(config)# router ospf 1
Enables OSPF routing for the specified routing process and places the router in router configuration mode.
The process-name argument is any alphanumeric string no longer than 40 characters.
Note
Step 3 router-id { router-id }
Example:
RP/0/RP0/CPU0:router(config-ospf)# router id 192.168.4.3
Configures a router ID for the OSPF process.
We recommend using a stable IPv4 address as the router ID.
Note
Step 4 area area-id
Example:
RP/0/RP0/CPU0:router(config-ospf)# area 1
Enters area configuration mode.
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.
Step 5 interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-ospf-ar)# interface TenGigE 0/0/0/0
Enters interface configuration mode and associates one or more interfaces to the area.
Step 6 authentication[ message-digest keychain | keychain keychain | null]
Configures an MD5 keychain. Keychains can be configured at the following three levels of authentication:
• Router-level authentication
• Area-level authentication
• Interface-level authentication
Example:
The following example shows the configuration for keychain authentication.
RP/0/RP0/CPU0:router(config-ospf)# authentication keychain test_chain ----- Router-level
