Hi Arie,

That's what I also stumbled upon but I noticed it says that MPLSoMGRE 
should be supported but then I only spot p2p Tunnel interfaces and I'm 
not sure if some small detail escapes my site or how I can configure a 
multipoint tunnel interface:)
That would be step one and step 2 figuring out the route-map equivalent 
that would then build a tunnel to the nexthop received as it was the 
case with IOS XE.

Have a feeling that I will get some headaches along the way..this is not 
really a very detailed/documented topic.
