As pointed out above Disagree. load-sharing or router preferences were/are never a general case IMO and hence i disagree with MUST. > the "Default Router Preferences and More-Specific Routes" mechanisms > provides a simple mechanisms to cause the hosts to not see the routers as > equivalent if one so desires. > > Regards, > Bob > > > -------------------------------------------------------------------- > IETF IPv6 working group mailing list > [EMAIL PROTECTED] > Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 > -------------------------------------------------------------------- > -------------------------------------------------------------------- IETF IPv6 working group mailing list [EMAIL PROTECTED] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
