# IPv6_rpfilter
# Performs reverse path filtering (RPF) on IPv6 packets as per RFC 3704.
# Possible values:
#   - strict: Performs "strict" filtering as per RFC 3704. This check
#             verifies that the in ingress interface is the same interface
#             that would be used to send a packet reply to the source. That
#             is, ingress == egress.
#   - loose: Performs "loose" filtering as per RFC 3704. This check only
#            verifies that there is a route back to the source through any
#            interface; even if it's not the same one on which the packet
#            arrived.
#   - strict-forward: This is almost identical to "strict", but does not perform
#                     RPF for packets targeted to the host (INPUT).
#   - loose-forward: This is almost identical to "loose", but does not perform
#                    RPF for packets targeted to the host (INPUT).
#   - no: RPF is completely disabled.
