If the full IP6 is not negotiated, then the IPv6 routes get in the
header "X-CSTP-Split-Include:". As you describe the anyconnect client
doesn't seem to understand that. 

David's commit at:
http://git.infradead.org/users/dwmw2/openconnect.git/commitdiff/e9b90e7b
seem to suggest that there is no route passing in that case. I'm
wondering whether that client would be able to parse a custom header of
"X-CSTP-Split-Include-IP6". If that doesn't work we'll have to figure
out how and if an anyconnect server is able to send such routes.
