Hello Yakov,

Two small corrections, under 6PE-ALT:

1) ?? = Francois Le Faucheur

2) I brought up one additional issue: with the lack of explicit  
signaling as proposed in 6PE-ALT, BGP routers could not disambiguate  
between:
	- an environment where IPv6 traffic is to be carried over IPv4 MPLS  
(ie a real 6PE scenario), and
	- an environment where IPv6 traffic is to be carried natively as  
IPv6 but where the native IPv6 addresses just happen to be IPv4- 
mapped addresses.

Thanks

Francois
