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

Configure BFD parameters (you can use default BFD parameters instead):
# Configure Router A.
[RouterA] bfd session init-mode active

{
Configure the minimum interval for transmitting BFD control packets as 500 milliseconds.

{
Configure the minimum interval for receiving BFD control packets as 500 milliseconds.
[RouterA-GigabitEthernet3/1/2] bfd min-receive-interval 500
{
Configure the detect multiplier as 7.
