OSPF Example
This example consists of:
Enabling OSPF with backbone area (Area 0) on one interface
Enabling OSPF on Area 1 on another interface
Summarizing/aggregating 205.226.24 network from Area 0 to Area 1
In this diagram:
GW-1 and GW-3 are gateways.
Controller 2 is an area border router with
- Interface atm-s1p1c0s2p1c0 on backbone area (Area 0)
- Interface atm-s1p1c0s3p1c0 on Area 1.
Controller 1 and GW-1 are on the backbone area.
GW-3 is on the area 1.
The routes in Area 0 are learned by GW-3 when the area border router
(Controller 2) injects summary link state advertisements (LSAs) into Area
1.

- First configure the interfaces as in Interface
Configuration Example.
- Initiate a clearVISN IP Switch Manager session to Controller 2.
