        Grr, no. This feature does not match the thread's subject :)
If the admin moves cables the medium_id values must be reconfigured.
This is a static mapping. You have to teach the kernel by hand :)
Then you can expect that remote broadcasts are received on all your
interfaces attached to this medium. May be you can avoid announcing
same VMAC through devices attached to same medium but I already don't
remember the issue. May be there can be specific policy for devices
attached to same hub, if you see something useful, of course, I already
forgot the VRRP terms and situation :) Just for FYI.
