Hi,

Do you know of any implementation of encap safi? The last time I checked FRRouting/Quagga had the only one?

RRouting has/had support for both the encap SAFI (RFCs 5512 and 5566) and encap attribute. Support for the safi was disabled, see [1], in anticipation of the encap safi being deprecated by the IETF in https://tools.ietf.org/html/draft-ietf-idr-tunnel-encaps-11

Just reverse these changes if you want to experiment with encap safi.

This said, there have been some proposals in the IETF for 'SD-WAN' related extensions that could use encap safi, but they are currently proposing a new safi...

   BGP has a SFAI named Tunnel Encapsulation, it is important in overlay scenario.More detail can be found in the RFC 5512 and RFC 5566.
   Is there any plan to develop this  AFI/SAFI in BGP?
   Thanks！
