L3VPN and BGP add-path

[Marcel Menzel]

Hello List,


I am running the new MPLS L3VPN feature for quite a while now, and it's 
working without issues so far for me, but I have one question:

I set "add paths on;" on my iBGP peer template in all SAFIs and while it 
was running successfully before the migration to L3VPN, the additional 
routes in the RIB are now gone, but the capabilities are still exchanged 
between peers.
Furthermore, I can't set "add paths on;" property for any SAFI in the 
L3VPN protocol, this might be the reason why those additional routes are 
missing?

My only question now is if this just hasn't been implemented yet with 
BIRD (I am just being curious hence I'm asking), my config is something 
missing or this being the general fact that add-path with MPLS L3VPN 
simply is not a thing with other vendors aswell (to be fair, I've never 
seen an L3VPN network with add-path enabled in production so far).


Thanks for the heads-up in advance,

Marcel
