All,

Under one Tenant created 1 network with 2 subnets [10.10.10.0/24 and
20.20.20.0/24] and 1 Router with 2 interfaces attached to corresponding
subnets.

1. Ping b/w same subnet VMs successful.
2. Ping to all Router/DHCP (10.10.10.1 & 2/20.20.20.1 & 2) from both
subnet VMs is successful
3. Ping across subnet VMs fails.

Am I missing something here, to reach across subnets ?
