Hi, 

Mitaka branch moved away from stable to mitaka-eol. Use stable/ocata or 
stable/newton branches. 

Thanks

Hi Raja, 

We are trying to do a three node setup following the steps mentioned in 
http://www.opencontrail.org/rdo-openstack-opencontrail-integration/ . 

We have till now achieved the below: 

1. Created three VMs with RHEL 7.2. 
2. Installed RDO Openstack Controller using Mitaka (single node setup) in one 
VM. 
3. Trying to setup OpenContrail controller on second VM (Encountered with 
errors,trying to resolve the same) 
4. Trying to setup vRouter on the third VM. For this I have setup a Repo (as 
mentioned in the link above) but still I am unable to install the packages 
mentioned in the link for ex. contrail-openstack-vrouter, contrail-vrouter etc. 

I am unable to understand the link/dependency of Opencontrail Vrouter Compute 
on Opencontrail Controller. Please guide me if I am following the right 
approach or suggest me the correct approach.

Hi 

Thanks for the reply. I am able to resolve this issue. 
I have also completed all the steps mentioned in the document - " 
https://github.com/Juniper/contrail-vrouter/tree/master ". 
My final ouput shows scons: done building targets . 
Also attaching the images of the compiled code. 

Can vrouter be installed and run standalone on a system or does it runs only 
after integration with opencontrail and openstack? 
Any document or link for installing and running Opencontrail vrouter will be 
appreciated.

As with all clustered software: you would want to run with at least 3 
(Cassandra) nodes for quorum reasons. 



There are probably some Cassandra settings you can tweak to make it functioning 
when doing a 2 node cluster but I would not recommend using that in production.

Hi Raj, 

I am using cloudwatt specific version. 

One more observation, 

In the DISCOVERY (http://localhost:5998/services), Collector service shows down 
for 30 - 60 seconds during the switchover. Is that expected behavior? 

Thanks

we have multiple stable releases after that.

In 2.21 the architecture is different, collector will establish one connection 
to one cassandra server per generator. If that fails, it will retry the next 
server. This is evident from the collector logs. It seems that you are getting 
TimedOutException which suggests your single remaining cassandra node might be 
getting overloaded. 





If you check using netstat -anp for contrail-collector pid you should be seeing 
connections to the 10.10.10.5 cassandra node.

cassandra supports active/active or cluster consisting of multiple active nodes
