Configuration procedure
1. Configure IP addresses and masks for interfaces, including the loopback interfaces, as shown
in Figure 16 . (Details not shown.)
2. Configure OSPF on each switch to ensure IP connectivity between them:
# Configure Switch A.
system-view
[SwitchA] ospf
[SwitchA-ospf-1] area 0
[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] network 10.1.1.0 0.0.0.255
[SwitchA-ospf-1-area-0.0.0.0] network 11.1.1.0 0.0.0.255
[SwitchA-ospf-1-area-0.0.0.0] quit
[SwitchA-ospf-1] quit
# Configure Switch B.
system-view
[SwitchB] ospf
[SwitchB-ospf-1] area 0
[SwitchB-ospf-1-area-0.0.0.0] network 2.2.2.9 0.0.0.0
[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 20.1.1.0 0.0.0.255
[SwitchB-ospf-1-area-0.0.0.0] quit
[SwitchB-ospf-1] quit
# Configure Switch C.
system-view
[SwitchC] ospf
[SwitchC-ospf-1] area 0
[SwitchC-ospf-1-area-0.0.0.0] network 3.3.3.9 0.0.0.0
[SwitchC-ospf-1-area-0.0.0.0] network 20.1.1.0 0.0.0.255
[SwitchC-ospf-1-area-0.0.0.0] network 21.1.1.0 0.0.0.255
[SwitchC-ospf-1-area-0.0.0.0] quit
[SwitchC-ospf-1] quit
# Verify that the switches have learned the routes to each other. For example, on Switch A:
[SwitchA] display ip routing-table
