<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Happy new year to everyone!!! <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have an odd issue with a vyos deployment running OSPF, for some reason the OSPF instance keeps flapping and by flapping it drops all routes then goes through with the SFP process this happens every 1-2 times an hour on both physical links
facing the network we have about 4 other peers in the area and they run without any issues however they are cisco routers and not a vyos instance.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have deployed and management vyos routers for over a couple of years now first time every running into an issue like this.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have checked IGMP flooding I understand OSPF does not join a multicast group this feature is currently disabled on layer 2 has not made any difference.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Anyone else come across this problem? I’ve run out of ideas!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">.199 is the virtual vyos router (loopback interface)<o:p></o:p></p>
<p class="MsoNormal">.70 And .102 is the physically connected interfaces on the virtual firewall<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The rest are ip addresses of the neighbouring routers that are part of the same ospf area.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any feedback would be great. Please relay back offline don’t want to flood the list with a massive email chain.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
