The VPN technology includes L2VPN technology and L3VPN technology based on MPLS tradition, and EVPN technology. Generally, the outer layer tunnel and the inner layer VPN label required by the VPN may be formed by MPLS, which may be implemented based on protocols such as LDP, MP-BGP, etc. But in the case that the intermediate network node traversed by the VPN does not support MPLS, but supports IP and GRE, the outer layer tunnel required by the VPN can be formed by selecting GRE, and the inner layer VPN label is still formed by the VPN nodes of which both ends support MPLS through the relevant protocol. Under the condition that an intermediate network is complex or has a specific networking requirement, the VPN nodes at two ends are connected through multi-segment GRE splicing to form a required outer tunnel.
