Configuration procedure
1. Configure IPv6 addresses for interfaces and IPv4 addresses for loopback interfaces. (Details
not shown.)
2. Configure IBGP and EBGP connections and advertise network routes through IPv6 BGP:
# Configure Switch A.
<SwitchA> system-view
[SwitchA] bgp 100
[SwitchA-bgp-default] router-id 1.1.1.1
[SwitchA-bgp-default] peer 100::2 as-number 200
[SwitchA-bgp-default] address-family ipv6
[SwitchA-bgp-default-ipv6] peer 100::2 enable
[SwitchA-bgp-default-ipv6] network 1:: 64
[SwitchA-bgp-default-ipv6] network 100:: 96
[SwitchA-bgp-default-ipv6] quit
[SwitchA-bgp-default] quit
# Configure Switch B.
<SwitchB> system-view
[SwitchB] bgp 200
