Configuring Tunnel Protocols
This section describes how to configure the ANG’s two supported tunnel
protocols:
H Point-to-Point Tunneling Protocol (PPTP) developed by Microsoft,
3Com and others that uses Point-to-Point (PPP) protocol and Generic
Routing Encapsulation (GRE) to route packets through the Internet.
H IP Security (IPSec) protocol developed by the Internet Engineering
Task Force (IETF) that adds security extensions for encryption and
message authentication to IP protocol.
