Dan, Something is not adding up in your setup. All three controllers should not be the master. I am cc’ing the HA team members to follow up with you regarding this issue.
Thanks, Sunil From: Dan Houtz <[email protected]<mailto:[email protected]>> Date: Thursday, August 20, 2015 at 9:05 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [Users] Problems with VRRP/Keepalived on HA install Hi everyone, We are currently working on our first HA build of Contrail as up until not we've only tested on single node installs. At this point the install seems to work well but we are seeing issue with keepalived and the VIP address. For some odd reason all 3 Contrail nodes are master for the VIP despite tcpdump showing each box receiving vrrp multicast packets from each other and showing each with a different priority. Should the mcast packets be sources from the VIP? I see our Juniper boxes source their VRRP packets from interfaces local address. I've done plenty of VRRP on hardware routers but don't have any previous experience with keepalived so If anyone has any pointers it would be greatly appreciated. If there is any other data that would help to diagnose I am happy to provide it. Thanks!
