Configuration procedure
1.
Configure IPv6 addresses for interfaces. (Details not shown.)
2.
Configure OSPFv3 so that Switch A and Switch C can reach each other. (Details not shown.)
3.
Configure IPv6 BGP on Switch A:
# Establish two IBGP connections to Switch C.
<SwitchA> system-view
[SwitchA] bgp 200
[SwitchA-bgp] router-id 1.1.1.1
[SwitchA-bgp] peer 3001::3 as-number 200
[SwitchA-bgp] peer 2001::3 as-number 200
[SwitchA-bgp] address-family ipv6
[SwitchA-bgp-ipv6] peer 3001::3 enable
[SwitchA-bgp-ipv6] peer 2001::3 enable

# Create IPv6 ACL 2000 to permit 1200::0/64 to pass.

[SwitchA-acl6-basic-2000] quit
# Create two route policies, apply_med_50 and apply_med_100. Policy apply_med_50 sets the
MED for route 1200::0/64 to 50. Policy apply_med_100 sets that to 100.

# Apply routing policy apply_med_50 to routes outgoing to peer 3001::3, and apply routing
policy apply_med_100 to routes outgoing to peer 2001::3.

4.
Configure IPv6 BGP on Switch C:
# Establish two IBGP connections to Switch A.
