The IESG has received a request from the Operations and Management Area Working Group WG (opsawg) to consider the following document: - 'Alternate Tunnel Encapsulation for Data Frames in CAPWAP' <draft-ietf-opsawg-capwap-alt-tunnel-10.txt> as Experimental RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-12-13. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract Control and Provisioning of Wireless Access Points (CAPWAP) defines a specification to encapsulate a station's data frames between the Wireless Transmission Point (WTP) and Access Controller (AC). Specifically, the station's IEEE 802.11 data frames can be either locally bridged or tunneled to the AC. When tunneled, a CAPWAP data channel is used for tunneling. In many deployments encapsulating data frames to an entity other than the AC (for example to an Access Router (AR)) is desirable. Furthermore, it may also be desirable to use different tunnel encapsulation modes between the WTP and the Access Router. This document defines extension to CAPWAP protocol for supporting this capability and refers to it as alternate tunnel encapsulation. The alternate tunnel encapsulation allows 1) the WTP to tunnel non-management data frames to an endpoint different from the AC and 2) the WTP to tunnel using one of many known encapsulation types such as IP-IP, IP-GRE, CAPWAP. The WTP may advertise support for alternate tunnel encapsulation during the discovery and join process and AC may select one of the supported alternate tunnel encapsulation types while configuring the WTP.
