Configure the IGP on Ps and SPEs on the MPLS backbone network to implement IP connectivity.
Implement the connectivity between SPEs on the VPLS fully-connected network.

When VPN services need to be transmitted over a specified TE tunnel or when load balancing needs to be performed among multiple tunnels to fully use network resources, tunnel policies need to be applied to VPNs.
