Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure OSPF in AS 200 to ensure connectivity among Switch B, Switch C and Switch D.
(Details not shown.)
3. Configure BGP connections:
# Configure Switch A to establish EBGP sessions with Switch B and Switch C, and advertise
network 1.1.1.1/32.
<SwitchA> system-view
[SwitchA] bgp 100
[SwitchA-bgp] router-id 1.1.1.1
[SwitchA-bgp] peer 10.1.1.2 as-number 200
[SwitchA-bgp] peer 30.1.1.3 as-number 200
[SwitchA-bgp] address-family ipv4 unicast
[SwitchA-bgp-ipv4] peer 10.1.1.2 enable
[SwitchA-bgp-ipv4] peer 30.1.1.3 enable
[SwitchA-bgp-ipv4] network 1.1.1.1 32
# Configure Switch B to establish an EBGP session with Switch A, and an IBGP session with Switch
D.
