From: David Ahern <dsah...@gmail.com> RTA_VIA was added for MPLS as a way of specifying a gateway from a different address family. IPv4 and IPv6 do not currently support RTA_VIA so using it leads to routes that are not what the user intended. Catch and fail - returning a proper error message.
MPLS on the other hand does not support RTA_GATEWAY since it does not make sense to have a nexthop from the MPLS address family. Similarly, catch and fail - returning a proper error message.
