Rather than using the VRF device index and full FIB lookups, packets to/from these addresses should use direct FIB lookups based on the VRF device table. Multicast routes do not make sense for the L3 master device directly. Accordingly, do not add mcast routes for the device, and the VRF driver should fail attempts to send packets to ipv6 mcast addresses on the device (e.g, ping6 ff02::1% should fail) With this change connections into and out of a VRF enslaved device work for multicast and link-local addresses (icmp, tcp, and udp). e.g., 1. packets into VM with VRF config: ping6 -c3 fe80::e0:f9ff:fe1c:b974%br1 ping6 -c3 ff02::1%br1 ssh -6 fe80::e0:f9ff:fe1c:b974%br1 2. packets going out a VRF enslaved device: ping6 -c3 fe80::18f8:83ff:fe4b:7a2e%eth1 ping6 -c3 ff02::1%eth1 ssh -6 root@fe80::18f8:83ff:fe4b:7a2e%eth1 ==================== Signed-off-by: David S.
