• Enable OSPF on all the switches.

• Split the AS into three areas.

• Configure Switch A and Switch B as ABRs.

• Configure Switch C as an ASBR to redistribute external routes (static routes).

Configuration procedure

1. Configure IP addresses for interfaces. (Details not shown.)

2. Enable OSPF (see "Basic OSPF configuration example")

3. Configure OSPF to redistribute routes:

# On Switch C, configure a static route destined for network 3.1.2.0/24.

<SwitchC> system-view

[SwitchC] ip route-static 3.1.2.1 24 10.4.1.2

# On Switch C, configure OSPF to redistribute static routes.

[SwitchC] ospf 1

[SwitchC-ospf-1] import-route static

Verifying the configuration

# Display the ABR/ASBR information of Switch D.

<SwitchD> display ospf abr-asbr
