When using IPv6 within a single L2 network segment it is possible and
sometimes desirable to enable layer 2 devices to drop rogue RAs
before they reach end-nodes.  In order to distinguish valid from
rogue RAs, the L2 devices can use a spectrum of criteria, from a
static scheme that blocks RAs received on un-trusted ports, or from
un-trusted sources, to a more dynamic scheme that uses Secure
Neighbor Discovery (SEND) to challenge RA sources.

This document reviews various techniques applicable on the L2 devices
to reduce the threat of rogue RAs.
