Re: which interface to choose to send to destination link-local address - any RFC?

Opening the thread again. In my server I have #19 vlans configured on 10Gb Ethernet card. I don't know on which vlan the destination link-local address is. 1. As a user am I supposed to do ping6 on all of them one by one? 2. How does the TCP will work? Open #19 connections to the destination

Hi, In IPv6 stack implementation, How IPv6 stack should select the outgoing interface to choose (when multiple interfaces) are available? Typically when the destination is the link-local address which may be on-link on both the interfaces (before the neighbor discovery) is done? Should IPv6

Thanks for the quick help. Good example of UDP. So in case of TCP, client which tries to connect to the server, should provide its link-local source address during socket(), bind() calls. Based on that IPv6 stack will figure out the out-going interface. Is that correct understanding? Regards,
