As noted earlier, the PPP Extensions working group agreed to the PPTP Forum proposal at the June 1996 IETF meeting in Montreal. This includes converging PPTP and Cisco's Layer 2 Forwarding approach to tunneling. Microsoft and the other PPTP Forum companies are working to provide mutual compatibility between PPTP and Cisco's Layer 2 Forwarding (L2F) tunneling protocol. This is good news for users because regardless of which tunneling protocol they initially use, the other will be supported.
