3.9 OSPF Configuration Examples

Note:
These examples only cover commands for OSPF configuration.
3.9.1 Configuring OSPF Basic Functions
I. Network requirements
As shown in the following figure, all switches run OSPF. The AS is split into three areas,
in which, Switch A and Switch B act as ABRs to forward routing information between
areas.
After configuration, all switches can learn routes to every network segment in the AS.
