BCPs are stable identifiers for Best Current Practices. A BCP may consist of a single RFC or a group of RFCs related to a specific IETF process or recommended guidelines. The collection may become empty as the BCP evolves.

Abstract
This document specifies a mechanism for protecting hosts connected to a switched network against rogue DHCPv6 servers. It is based on DHCPv6 packet filtering at the layer 2 device at which the packets are received. A similar mechanism has been widely deployed in IPv4 networks ('DHCP snooping'); hence, it is desirable that similar functionality be provided for IPv6 networks. This document specifies a Best Current Practice for the implementation of DHCPv6-Shield.
