Configuration procedure
1. Configure IP addresses and masks for the interfaces according to Figure 26. (Details not shown.)
2. Configure OSPF to advertise routes within the ASs:
# Configure OSPF on Router A.
<RouterA> system-view
[RouterA] ospf
[RouterA-ospf-1] area 0
[RouterA-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[RouterA-ospf-1-area-0.0.0.0] network 1.1.1.9 0.0.0.0
[RouterA-ospf-1-area-0.0.0.0] quit
[RouterA-ospf-1] quit
# Configure OSPF on Router B.
<RouterB> system-view
[RouterB] ospf
[RouterB-ospf-1] import-route direct
[RouterB-ospf-1] import-route bgp
[RouterB-ospf-1] area 0
[RouterB-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[RouterB-ospf-1-area-0.0.0.0] network 2.2.2.9 0.0.0.0
[RouterB-ospf-1-area-0.0.0.0] quit
[RouterB-ospf-1] quit
# Configure OSPF on Router C.
<RouterC> system-view
[RouterC] ospf
[RouterC-ospf-1] import-route direct
[RouterC-ospf-1] import-route bgp
