• 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).
Figure 23 Network diagram
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 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
Verifying the configuration
# Display the ABR/ASBR information on Router D.
<RouterD> display ospf abr-asbr
