This is not on production network. <br />
<br />
How about the serial subnet, the network subnet between each region to HQ, should I use <br />
172.16.7.224 / 30<br />
172.16.7.228 / 30<br />
172.16.7.232 / 30 <br />
<br />

Need to subnet 172.16.0.0/16 across 4 regions and support the following nodes<br />
<br />
A1 : 510<br />
HQ: 300<br />
A2 255<br />
A3: 168<br />
<br />
Any comment for the network ID used in each region, together with the WAN subnet used in each router ? HQ connect to each region in hub-and-spoke network.
