Configuration procedure
1. Configure IP addresses and masks for interfaces. (Details not shown.)
2. Configure OSPF to advertise routes within the ASs, and redistribute the direct and BGP routes into
OSPF on Switch B and Switch C:
# Configure Switch A.
<SwitchA> system-view
[SwitchA] ospf
[SwitchA-ospf-1] area 0
[SwitchA-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[SwitchA-ospf-1-area-0.0.0.0] network 1.1.1.9 0.0.0.0
[SwitchA-ospf-1-area-0.0.0.0] quit
[SwitchA-ospf-1] quit
# Configure Switch B.
<SwitchB> system-view
[SwitchB] ospf
[SwitchB-ospf-1] import-route direct
[SwitchB-ospf-1] import-route bgp
[SwitchB-ospf-1] area 0
[SwitchB-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255
[SwitchB-ospf-1-area-0.0.0.0] network 2.2.2.9 0.0.0.0
