Btw, the other problem with “two RTs” scheme might be mobility. The leaf
MAC-VRF can’t see each others sequence numbers for a MAC. Please
see/consider my prior email. Need to address E-Tree for non-MPLS encaps
and in DC settings (think PVLAN).

Hi guys,
If we instead consider that the two-RTs scheme from operator point-of-view
is really a Root-only and Leaf-only MAC-VRF scheme (vs mixed root/leaf
MAC-VRF). Suppose all routes from a leaf VRF are marked with a “leaf
indication”. Suppose we use only one RT where leaf MAC-VRF rejects any

Lots of thanks for a prompt response.
My conclusion js tbat the "two RTs" scheme should be used with special care in
E-tree solutions. This was not my impression from the first reading of 8317.
Since the "two RTs" scheme is very popular in hub-and-spoke" solutiobs for IP
VPN, the fact

I fully agree that tbe use case I've described can be addressed by the genegal
techniques of RFC 8317.

Hi Sasha,
The use case that you have described below is a legitimate use case and if we
look at what happens in RFC 7432 baseline, there is no flooding there because
MAC addresses among multi-homing PEs get synch’d up and thus even a PE in the
all-active multi-homing group doesn’t receive a
