TMM sends traffic from the host with a source MAC of an incorrect VLAN.
If an adjacent device uses a system similar to the BIG-IP system's auto-lasthop feature, it may use this incorrect MAC to send return traffic to the BIG-IP system, which will be dropped.
IPv6 route is added to the Linux host, either manually or by a dynamic routing protocol, but the host does not have a neighbor entry for the route nexthop.
Creating a neighbor entry for the nexthop address will resolve the problem. Note: A neighbor entry for the nexthop address is automatically created when the router probe interval expires. You can set this interval as low as 5 seconds using the ipv6.host.router_probe_interval database key. The neighbor entry is also created by manually pinging the nexthop address from the Linux host.
