Hi

I have successfully installed GNS IOU VM on Esxi server with IP-172.16.35.59 and installed GNS ER beta 2 on Windows7 which as its system IP as 172.16.35.150.
The issue is when I add the IOU switch's they communicate each other without any issues which is binded to server 172.16.35.59.
but when I connect IOS router to the IOU switch's and configure and try to communicate each other no go!!!!.
IOS routers are in local server binded to 172.16.35.150.
Router are able to ping google.com and able to go online, but not able to ping the IOU switch's
Please advice. I think am doing some mistake not able to figure out.

Hi,

We all know that ROUTER splits network. It means that your ROUTER's each side belongs to different network. SWITCH on the other hand works differently, why? Because it GROUP hosts as one network unlike in ROUTER where it divide GROUPS into multiple GROUPS. So, you say that the problem only occurred when ROUTER got involved in the network.

By means of this, you need to check the following:

NETWORK/SUBNET where each side of the ROUTER belongs to. You need to check the corresponding SUBNET Mask you used for both group.

ROUTING PROTOCOL - you must check the routing protocol it this is configured into the ROUTER. The function of the Routing Protocol is to route Packet from one network to another. You need to enable routing protocols like RIP, OSPF, EIGRP or Static Routing Protocol.

If these two configure correctly, your network design will work successfully.

I hope it would help you!
