III. Configuration procedure
Note:
This configuration procedure has omitted configurations between PE and P, and
configurations on CEs. For these details refer to the former example.
1) Configure PE-A:
# Configure VPN-instance 1 for VPN1 on PE-A, so that it can send and receive VPN
routing information of VPN-target 111:1.
[PE-A] ip vpn-instance vpn-instance 1
[PE-A-vpn-1] route-distinguisher 100:1
[PE-A-vpn-1] vpn-target 111:1 both
[PE-A-vpn-1] quit
# Set up MP-EBGP adjacency between PE-A and CE-A, import intra-CE-A VPN routes
learned into MBGP VPN-instance address family.
