Apply routing policy apply_med_50 to routes outgoing to peer 3002::2, and apply routing
policy apply_med_100 to routes outgoing to peer 2002::2.

# Configure BFD over the link to peer 3002::2 so that when the link SecPath A<—>Router
B<—>Router C fails, BFD can quickly detect the failure and notify it to IPv6 BGP, and then the link
SecPath A<—>Router D<—>Router C takes effect immediately.

4. Configure IPv6 BGP on Router C:
system-view
[RouterC] bgp 200
[RouterC-bgp] ipv6-family
[RouterC-bgp-af-ipv6] peer 3001::1 as-number 200
[RouterC-bgp-af-ipv6] peer 3001::1 bfd
[RouterC-bgp-af-ipv6] peer 2001::1 as-number 200
[RouterC-bgp-af-ipv6] quit
[RouterC-bgp] quit
5. Configure BFD parameters (you can use default BFD parameters instead):
# Configure SecPath A.
[SecPathA] bfd session init-mode active
[SecPathA] interface GigabitEthernet0/2
{
Configure the minimum interval for transmitting BFD control packets as 500 milliseconds.
[SecPathA-GigabitEthernet0/2] bfd min-transmit-interval 500
{
Configure the minimum interval for receiving BFD control packets as 500 milliseconds.
[SecPathA-GigabitEthernet0/2] bfd min-receive-interval 500
{
Configure the detect multiplier as 7.
[SecPathA-GigabitEthernet0/2] bfd detect-multiplier 7
{
Configure the BFD authentication mode as plain-text authentication, and set the authentication
key to ibgpbfd.
[SecPathA-GigabitEthernet0/2] bfd authentication-mode simple 1 ibgpbfd
[SecPathA-GigabitEthernet0/2] quit
# Configure Router C.
