There is generally an issue (ie, unreadable stream) if both servers send
on the same UDP port. A solution is to use source specific multicast,
that allows to choose the server. VLC supports this, but you need
support of igmpv3 and likely of PIM-SSM (perhaps other multicast routing
protacols support source multicast as well) on your network.
