Configure Switch A:
# Configure IP addresses for interfaces. (Details not shown.)
# Configure the EBGP connection.
<SwitchA> system-view
[SwitchA] bgp 65008
[SwitchA-bgp] router-id 1.1.1.1
[SwitchA-bgp] peer 200.1.1.1 as-number 65009
# Enable GR capability for BGP.
[SwitchA-bgp] graceful-restart
# Inject network 8.0.0.0/8 to the BGP routing table.
[SwitchA-bgp] address-family ipv4
[SwitchA-bgp-ipv4] network 8.0.0.0
# Enable Switch A to exchange IPv4 unicast routing information with Switch B.
[SwitchA-bgp-ipv4] peer 200.1.1.1 enable
2.
Configure Switch B:
# Configure IP addresses for interfaces. (Details not shown.)
# Configure the EBGP connection.
