When using IPv6 within a single L2 network segment it is neccesary to
ensure that all routers advertising their services within it are
valid.  In cases where it is not convinient or possible to use SeND
[RFC3971] a rogue Router Advertisement (RA) [RFC4861] could be sent
by accident due to misconfiguraton or ill intended.  Simple solutions
for protecting against rogue RAs are beneficial in complementing SeND
in securing the L2 domain for ceratin types of devices or in certain
transitional situations.
This document proposes a solution to reduce the threat of rogue RAs
by enabling layer 2 devices to forward only RAs received over
designated ports.
