<div dir="ltr"><div><div><div>Hello Yong Sheng Gong!<br><br></div>Apologies for the lateness of my reply (I've been intermittently available over the last month and am now just catching up on ML threads). Anyway, did you get your question answered elsewhere? It looks like you've discovered a bug in the behavior here-- when you created the member on server_subnet2, an interface should have been added to the amphora in the amphora-haproxy namespace. If you haven't yet filed a bug report on this, could you?<br><br></div>In any case, the behavior you're seeing (which is not correct in this case) is that if the amphora doesn't have a directly-connected interface is that it will use its default route to attempt to reach the member.<br><br></div>Stephen<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, May 10, 2016 at 12:01 AM, 龚永生 <span dir="ltr"><<a href="mailto:gong.yongsheng@99cloud.net" target="_blank">gong.yongsheng@99cloud.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="line-height:1.7;color:#000000;font-size:14px;font-family:Arial"><div>Hi, Stephen,</div><div><br></div>
