A representation of an IPv6 endpoint/connection.
This class provides an Internet four-tuple (source and destination ports and addresses). These are used in the ns3::Ipv6EndPointDemux as targets of lookups. The class also has a callback for notification to higher layers that a packet from a lower layer was received. In the ns3 internet-stack, these notifications are automatically registered to be received by the corresponding socket.

Bind a socket to specific device.
This method corresponds to using setsockopt() SO_BINDTODEVICE of real network or BSD sockets. If set on a socket, this option will force packets to leave the bound device regardless of the device that IP routing would naturally choose. In the receive direction, only packets received from the bound interface will be delivered.
This option has no particular relationship to binding sockets to an address via Socket::Bind (). It is possible to bind sockets to a specific IP address on the bound interface by calling both Socket::Bind (address) and Socket::BindToNetDevice (device), but it is also possible to bind to mismatching device and address, even if the socket can not receive any packets as a result.
