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 

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...
