2. Configure BGP connections:
# Configure Switch A.
<SwitchA> system-view
[SwitchA] bgp 100
[SwitchA-bgp-default] router-id 1.1.1.1
[SwitchA-bgp-default] peer 192.1.1.2 as-number 200
[SwitchA-bgp-default] address-family ipv4 unicast
[SwitchA-bgp-default-ipv4] peer 192.1.1.2 enable
# Inject network 20.0.0.0/8 to the BGP routing table.
[SwitchA-bgp-default-ipv4] network 20.0.0.0
[SwitchA-bgp-default-ipv4] quit
[SwitchA-bgp-default] quit
