Is it possible in boost.asio to bind to a specific NIC with link local address?

Question

as the asio documentation does not really live up to its name I have to ask this question. Help me Stackoverflow, you are my only hope ;)

We are talking in IPv6 here. I would like to tell asio to use a specific interface, like eth0, but without a global ip address, since I have only link local ones. I would like to have something simliar to ping6 -I . Is this possible with asio or do I have to use Berkeley Sockets for this?

Thank you in advance and best regards.

Answer 1

append the interface name after the IP address with a % delimiter

fe80::15c3:6bea:aaac:a016%eth0
