IPv6 BGP route reflector configuration example
Network requirements
As shown in Figure 83, run EBGP between Switch A and Switch B, run IBGP between Switch C and Switch B, and between Switch C and Switch D.
Configure Switch C as a route reflector with clients Switch B and Switch D.

Configuration procedure
Configure IPv6 addresses for interfaces and IPv4 addresses for loopback interfaces. (Details not shown.)
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 [SwitchB-bgp-default] router-id 2.2.2.2 [SwitchB-bgp-default] peer 100::1 as-number 100 [SwitchB-bgp-default] peer 101::1 as-number 200 [SwitchB-bgp-default] address-family ipv6 [SwitchB-bgp-default-ipv6] peer 100::1 enable [SwitchB-bgp-default-ipv6] peer 101::1 enable [SwitchB-bgp-default-ipv6] peer 101::1 next-hop-local [SwitchB-bgp-default-ipv6] network 100:: 96 [SwitchB-bgp-default-ipv6] network 101:: 96 [SwitchB-bgp-default-ipv6] quit [SwitchB-bgp-default] quit
# Configure Switch C.
<SwitchC> system-view [SwitchC] bgp 200 [SwitchC-bgp-default] router-id 3.3.3.3 [SwitchC-bgp-default] peer 101::2 as-number 200 [SwitchC-bgp-default] peer 102::2 as-number 200 [SwitchC-bgp-default] address-family ipv6 [SwitchC-bgp-default-ipv6] peer 101::2 enable [SwitchC-bgp-default-ipv6] peer 102::2 enable [SwitchC-bgp-default-ipv6] network 101:: 96 [SwitchC-bgp-default-ipv6] network 102:: 96
# Configure Switch D.
<SwitchD> system-view [SwitchD] bgp 200 [SwitchD-bgp-default] router-id 4.4.4.4 [SwitchD-bgp-default] peer 102::1 as-number 200 [SwitchD-bgp-default] address-family ipv6 [SwitchD-bgp-default-ipv6] peer 102::1 enable [SwitchD-bgp-default-ipv6] network 102:: 96
Configure Switch C as a route reflector, and configure Switch B and Switch D as its clients.
[SwitchC-bgp-default-ipv6] peer 101::2 reflect-client [SwitchC-bgp-default-ipv6] peer 102::2 reflect-client [SwitchC-bgp-default-ipv6] quit [SwitchC-bgp-default] quit
Verifying the configuration
# Execute the display bgp routing-table ipv6 command on Switch D.
[SwitchD] display bgp routing-table ipv6
Total number of routes: 5
BGP local router ID is 4.4.4.4

The output shows that Switch D has learned the network 1::/64 from Switch C through route reflection.
