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!
Dan
