Stefan,
We typically recommend 3 control nodes. But the control-node must be
meshed with an iBGP session.
Can you please verify that that is the case… ? All of the must show a
session to each other.
Hi Pedro,
where can we find documentation on how to configure/check that? :-)
Regards,
Stefan

Hi,
https://techwiki.juniper.net/Documentation/Contrail/Contrail_Controller_Feature_Guide/Configuration/50_Juniper_OpenStack_High_Availability
says 'A highly available deployment of Contrail requires at least two
control nodes, three config nodes (including analytics and webui) and
three database nodes.'
Though what we discover when running 3 contrail-control daemons (on
three server) is:
- vrouter connects to only 2 (always different, so sometimes on A && B,
sometimes A && C and sometimes B && C)
When doing so we also experience network unavailability on some compute
nodes:
513752 10.0.80.11:22 X.X.X.X:56149 6 (1)
(K(nh):27, Action:D(NoSrcRt), S(nh):27, Statistics:0/0 UdpSrcPort 63529)
or
252404 10.0.80.1:53 10.0.80.11:53119 17 (1)
(K(nh):28, Action:F, S(nh):4, Statistics:0/0 UdpSrcPort 64509)
When stopping the third contrail-control daemon everything seems to work
fine again.
Is it architectually possible to run more than 2 contrail-control nodes?

Stefan
Hello,
can someone point us in the right direction?
