I then shove my /24's, /27's etc on the VRRP interfaces and they just work. :)</div><div><br></div><div>HTH</div><div><br></div><div>--DG</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, 2 Sep 2020 at 12:23, Rhys Cuff (Speedweb Internet) <<a href="mailto:Rhys@team.speedweb.com.au">Rhys@team.speedweb.com.au</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p class="MsoNormal">Hi Guys<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Has anyone had much experience with using Vrrp on a Mikrotik?<u></u><u></u></p>
<p class="MsoNormal">It seemed pretty easy to setup but the manual said the floating IP must be a /32 and to put an IP on the physical interface with a /24<u></u><u></u></p>
<p class="MsoNormal">This seemed wrong so I just put a /24 on the Vrrp interface and a completely different subnet on the physical interface for the routers to communicate.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Thinking I was clever all was well till about 1am two days after I did this, then it completely failed, switching back and forth from master to backup, basically having two masters on and off.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Is having a /32 on the vrrp really necessary, if so why?<u></u><u></u></p>
<p class="MsoNormal">Why would it have been all good for two days?<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">So my config that lasted two days<u></u><u></u></p>
<p class="MsoNormal">Vrrp <a href="http://192.168.1.1/24" target="_blank">192.168.1.1/24</a> (floating IP I care about)<u></u><u></u></p>
<p class="MsoNormal">Physical <a href="http://10.0.1.1/24" target="_blank">10.0.1.1/24</a> (to communicate with master/backup routers)<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">How the manual says to do it<u></u><u></u></p>
<p class="MsoNormal">Vrrp <a href="http://192.168.1.1/32" target="_blank">192.168.1.1/32</a><u></u><u></u></p>
<p class="MsoNormal">Physical <a href="http://192.168.1.2/24" target="_blank">192.168.1.2/24</a><u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Doing it the second way will mean a lot more IP’s/config as I want to have around 20 floating IP’s
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Thanks again for any help.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
