John, 

Our intent of using Encapsulation Extended Community is to indicate that Client routes need to be forwarded by a tunnel, 
but there is too much information about the  Tunnel attributes to be included in the Client route advertisement and those attributes are associated with the WAN ports (instead with Client Routes). 

We need to interpret the "barebones" as a hook to inform the peer nodes to use information carried in  the second UPDATE to establish the tunnel for the Client routes. 

I don't understand why RFC9012 doesn't allow this. What harm does it cause?

Linda
