# ip netns exec qrouter-f3554f15-78c0-4402-8df5-55ebb8da3f4c
sysctl net.ipv4.ip_forward<br>
net.ipv4.ip_forward = 1<br>

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

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 ?<br>
