Hi, Marc, Normally, host vendors normally really do not like to open this interface, but anyhow it is more solution oriented, let's discuss it after. -Hui 2009/4/23 Marc Blanchet <marc.blanchet@xxxxxxxxxxx>: > Christian's suggestion is one way. not sure it is complete. > > but I don't agree with you (Deng): i.e. I think this suggestion is in > scope of MIF wg.

The application just needs to bind the socket to a specific IP address. Doing that ensures that packets sourced by the application will use the specified address, will go out through the interface corresponding to that address, and will use the default gateway associated with that interface. >>> >>> -- Christian Huitema >>> >>> >>> >>> _______________________________________________ >>> Ietf mailing list >>> Ietf@xxxxxxxx >>> https://www.ietf.org/mailman/listinfo/ietf >>> >> _______________________________________________ >> mif mailing list >> mif@xxxxxxxx >> https://www.ietf.org/mailman/listinfo/mif > > > -- > ========= > IPv6 book: Migrating to IPv6, Wiley. http://www.ipv6book.ca > Stun/Turn server for VoIP NAT-FW traversal: http://numb.viagenie.ca > DTN news service: http://reeves.viagenie.ca > > _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
