Issue Description
Which Types of Point-to-Point VPN Does the device Support?
The device supports GRE, IPSec, VLL, L2TP and SSL VPN.

The device supports L2TP and SSL VPN in V200R002C00 and later versions and supports VLL in V200R003C00 and later versions.

GRE tunnels can encapsulate unicast and multicast packets.

IPSec tunnels can only encapsulation and encrypt unicast packets. To encrypt multicast packets, use GRE over IPSec.

As a point-to-point (P2P) Layer 2 tunneling technology based on Multiprotocol Label Switching (MPLS), VLL allows data packets to traverse networks using different media.

L2TP tunnels transmit PPP packets over the public network, and support user authentication and remote access, but have low security. You can use L2TP over IPSec to improve security.

SSL VPN is based on the HTTPS protocol, and it uses the data encryption, user identity authentication, and message integrity check mechanisms of the SSL protocol to help ensure that remote access to enterprise intranets is safe and secure.
