  1. Create N1 with S1(ipV4) and S2(ipv6) and N2 wit S1(IPv4) and S2(IPv6)
  2. Boot All VM's
  3. Create router(R1) and associate both IPv4 and IPv6 subnets from both Network  to it.
  4. Verify ping across all VM's for both IPv4 and IPv6.

Hi RajaRajan,

I am not able to reproduce the issue. Could you please provide steps to reproduce and configurations/logs/flow-dumps etc.

I tested with below build:

https://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/org/opendaylight/integration/karaf/0.8.1-SNAPSHOT/karaf-0.8.1-20180328.221417-96.zip

 
Thanks,
Somashekar

Hi Rajarajan,

While reproducing the issue NETVIRT-1186 (here we boot vm's first and then create router and associate) , it was observed in dual-stack case ping was not working across VM's since the subnet entry was not available even after
associating to router. In dual-stack, subnet(ipv4/ipv6) whichever is associated first to router , only that entry will be available in fib, the second associated subnet is missed out.It could be ipv4/ipv6.
                The issue is not seen after putting the fix for jira-1171. It is tested after verifying with 4 VM's. 

            I have assigned defect to you for verification in scaled environment.

Regards

Nithi
