CEs of the same VPN can ping each other, whereas those of different VPNs cannot. For example,
CE 1 can ping CE 3 (6.6.6.9), but cannot ping CE 4 (7.7.7.9):
[CE1] ping 6.6.6.9

Configuring an MPLS L3VPN that uses a GRE tunnel
Network requirements
CE 1 and CE 2 belong to VPN 1. The PEs support MPLS. The P router does not support MPLS and provides
only IP functions.
On the backbone, use a GRE tunnel to encapsulate and forward VPN packets to implement MPLS
L3VPN.
Configure tunneling policies on the PEs and specify the tunnel type for VPN traffic as GRE. This
configuration is optional.
