Configuring OSPF route redistribution

Network requirements

• Enable OSPF on all the switches.

• Split the AS into three areas.

• Configure Switch A and Router B as ABRs.

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

Figure 21 Network diagram

Configuration procedure

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

2. Enable OSPF (see "Configuring basic OSPF").

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
