Hi Bo,

Few questions ...

1. How do you envision remote endpoints would know the src IP information ?

2. How can flooded or p2mp distributed information containing src addresses
of the packets valid in many ingress sites ? Please observe that each
ingress site would be very likely using a different src address(es).

3. How can you say that  "This memo asks the IANA for no new parameters."
if you are defining new TLVs ?

Thx,
Robert
