Hello Mach, Just be curious about the following: >>3. Add the missing part about that the local ASBR SHOULD do a "proxy" advertisement for the backward of an inter-AS TE link; What do you mean by "the backward of an inter-AS TE link"? Does that mean that local ASBR would advertise TE info about the incoming inter-AS link(s)? Thanks. Regards, Peng
