Huawei Vpn+gre Experiment

Experimental environment:

Here we use a Huawei s3526 switch to simulate Internet two H3C firewalls, two quidway s2403h-hi switches

Two 192.168.1.0 and 192.168.2.0 network segments are connected by the two sides of Huawei's firewall respectively

Achieving cheap connectivity using VPN technology

To allow two LANs to communicate with each other, the GRE tunneling technique is used between two firewalls (the so-called tunnels are logical virtual)

Experimental purposes:

The GRE tunneling technology is established on the basis of VPN to realize the interconnection between the LAN of 192.168.1.0 and 192.168.2.0 network segment.
