All,<br>

Under one Tenant created 1 network with 2 subnets [<a

<a moz-do-not-send="true"
href="http://20.20.20.0/24" target="_blank">20.20.20.0/24</a>]
and 1 Router with 2 interfaces attached to
corresponding<br>
subnets.<br>
<br>
1. Ping b/w same subnet VMs successful.<br>
2. Ping to all Router/DHCP (10.10.10.1 & 2/<a
moz-do-not-send="true" href="http://20.20.20.1"
target="_blank">20.20.20.1</a> & 2) from both<br>
subnet VMs is successful<br>
3. Ping across subnet VMs fails.<br>
<br>
Am I missing something here, to reach across subnets
