Bidirectional SFC not working on multinode setup
We are currently implementing SFC for the VNF's launched on plain Openstack(Ocata) and facing few issues mentioned below.
Problem Statement : "Bidirectional SFC in multi node setup is not working ,ping is working but wget and iperf traffic not working"
Devstack Setup:
1.Installed openstack-ocata on 2 nodes (1 controller+compute and 1 compute node)
2.Launched 4 vms on compute node while 1 VM is launched on controller node. Vms are Centos.And have enabled net.ipv4.ip_forward in all the VM's
3. vm1->vm2-
SFC Flow classifier points the logical source port to vm1 and the source ip prefix is the ip of vm1 and destination ip prefix is of vm5.
Reverse SFC Flow Classifier is also written.
4.Disabled port security group
5.Bidirectional SFC is working when all vms are launched on single compute node (even wget is working)
Queries:
1.Are there any other parameters that we need to set for multinode setup
2.Should mtu values be set? Because wget is working for files <KB (in bytes) on multinode setup
Local.conf file for controller and compute node:
printenv | grep OS_* for compute : https:/
Kindly advice and provide your inputs for the same.
