Hi Ted, Yes. In such Managed Networks, SLAAC is disabled and IPv6 addresses are only assigned using DHCPv6 server. Switches in such environments provide First Hop Security by gleaning DHCP/NDP messages and can make sure hosts are using the IPv6 addresses assigned by the DHCPv6 server only (Source Guard). With the technique in this draft only certain hosts will be permitted assignment of IA_TA and not for other hosts. --Tiru. _______________________________________________ mif mailing list [email protected] https://www.ietf.org/mailman/listinfo/mif
