The output shows that PE 1 has a route to the remote CE. Output on PE 2 is similar.
# Verify that CEs of the same VPN can ping each other, whereas those of different VPNs cannot. For
example, CE 1 can ping CE 3 (10.3.1.1), but it cannot ping CE 4 (10.4.1.1). (Details not shown.)

Configuring MPLS L3VPN over 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 features.
On the backbone, use a GRE tunnel to encapsulate and forward VPN packets to implement MPLS
L3VPN.
Configure tunnel policies on the PEs, and specify the tunnel type for VPN traffic as GRE.
