[Boost-users] Multiple binds on a asio socket

Hi,
 
Is it possible to have multiple binds on a single socket instance?
 
Say I have two multicast addresses that share the same port and use the
same nic.  On linux I would bind like so:
 
listenEndPoint1(multicastAddress1.to_v4(), port);
socket_.bind(listenEndPoint1);

socket_.set_option(asio::ip::multicast::join_group(multicastAddress1.to_
v4(), interfaceAddress.to_v4())); }

Can I then perform a second bind and join for the other multicast
address?
 
listenEndPoint2(multicastAddress2.to_v4(), port);
socket_.bind(listenEndPoint2);

socket_.set_option(asio::ip::multicast::join_group(multicastAddress2.to_
v4(), interfaceAddress.to_v4())); }

If this is not possible or good practice, what would be the alternative?

Regards,

Lee MacDonald
