[j-nsp] IPv6 uRPF + VRRPv3 packets dropped

Hello,

we're using IPv6 uRPF filter on a MX960 (IRB interface) and I noticed
that it drops VRRPv3 packets (source fe80::/64, destination ff02::12).
Is this expected behaviour? It makes sense to me to drop link-local
packets but shouldn't packets that go the RE be excluded from that?

It's easily fixable by using a custom fail-filter but I wonder if this
a bug or not.

Regards

Sebastian
