Configuring OSPF route redistribution

Network requirements

• Enable OSPF on all the routers, and split the AS into three areas.

• Configure Router A and Router B as ABRs.

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

Configuration procedure

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

2. Configure OSPF basic functions (see "Configuring OSPF basic functions").

3. Configure OSPF to redistribute routes:

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

<RouterC> system-view

[RouterC] ip route-static 3.1.2.1 24 10.4.1.2

# On Router C, configure OSPF to redistribute the static route.

[RouterC] ospf 1

[RouterC-ospf-1] import-route static

4. Verify the configuration:

# Display ABR/ASBR information on Router D.

<RouterD> display ospf abr-asbr
