Layer 2 Tunneling Protocol Overview
L2TP is defined in RFC 2661,Layer Two Tunneling Protocol (L2TP).
L2TP facilitates the tunneling of PPP packets across an intervening network in a way that is as transparent as possible to both end users and applications. It employs access profiles for group and individual user access, and uses authentication to establish secure connections between the two ends of each tunnel. Multilink PPP functionality is also supported.
The L2TP services are supported on the following routers only:
- M7i routers with AS PICs
- M10i routers with AS and MultiServices 100 PICs
- M120 routers with AS, MultiServices 100, and MultiServices 400 PICs
For more information, see L2TP Services Configuration Overview.
