After the configuration, run the display bgp vpnv6 all peer command on a PE, and you can see
that the BGP peer relation between the PE and CE is in Established state.
<PE1> display bgp vpnv6 all peer
BGP local router ID : 1.1.1.1
Local AS number : 100
Total number of peers : 2
Peer
3.3.3.3
Peer of vpn6 instance :

Step 7 On CE1, enable load balancing for the traffic from CE1 to CE2.
[CE1] bgp 65410
[CE1-bgp] ipv6-family unicast
[CE1-bgp-af-ipv6] maximum load-balancing 2
Step 8 Configure a routing policy. Increase the MED value of the BGP route advertised by PE3 to CE2
and ensure that the traffic from CE2 to CE1 can pass through PE4. PE3 functions as a backup.
[PE3] route-policy policy1 permit node 10
[PE3-route-policy] apply cost 120
[PE3-route-policy] quit
[PE3] bgp 100
