Linux now supports Virtual Routing and Forwarding (VRF) as per: https://www.kernel.org/doc/Documentation/networking/vrf.txt In order for an application to bind or connect to a socket with an address in a VRF, they need to first bind the socket to the VRF device: setsockopt(sd, SOL_SOCKET, SO_BINDTODEVICE, dev, strlen(dev)+1); Note "dev" is the VRF device, eg. VRF "blue", rather than an interface enslaved to the VRF. Add a new socket option, ZMQ_BINDTODEVICE, to bind a socket to a device. In general, if a socket is bound to a device, eg. an interface, only packets received from that particular device are processed by the socket. If device is a VRF device, then subsequent binds/connects to that socket use addresses in the VRF routing table.
