OSPF configuration example in the web interface

Network requirements

All the devices run OSPF, and the AS is divided into three areas.

SecPath and Device A act as ABRs to forward routes between areas.

Configure Area 1 as an NSSA area, and configure Device B as an ASBR to redistribute static routes

into the AS.
