Currently, IPv6 is enabled by default on eth0 and macvlan0@eth0 interface on host OS. During system bootup or the management interface coming up, the management interface (i.e., eth0 and macvlan0@eth0 interface) on the host OS might respond to IPv6 Neighbor Discovery protocol packets. It could cause the upstream router to learn the MAC address of eth0 and macvlan0@eth0 interface instead of fxp0 interface in Junos. In certain deployments (based on the upstream router configurations), the upstream router might disable the access to fxp0 interface.
