DO NOT ASK FOR
The following example will show how to establish a connection between iou-web and GNS3 using VMware Workstation. VMWare vSphere can be used also.
VMware Workstation allows to manage vSwitches (Edit -> Virtual Network Editor):
By default three Virtual Network (vSwitches) are present:
- Bridged: the VM will share the physical link of the computer host.
- Host-only: the VM will be connected to a routed and separated network. The computer host will act as DHCP/DNS server and as default gateway.
- NAT: as Host-only but computer host will NAT VM IP to external networks.
Many Host-only and NAT Virtual network can be created, but only one Bridged network per physical adapter can exists.
The Host-only network will be used. The iou-web VM must be configured as following:
The following NETMAP is used:
ID 1 is a simple IOU instance, ID 2 is a Cloud instance bound to eth1:
Save the lab and start both R1 and Cloud:
Now R1 should be able to ping computer host, if the firewall is disabled:
Router-IOU#ping 192.168.245.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.245.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 4/5/8 ms
Now start GNS3, add a Cloud device and another GNS3 emulated router. Configure the Cloud to use the VMnet1 adapter:
If not VMnet adapter is present, try to restart npf service:
net stop npf net start npf
Start the GNS3 router and assign an IP address in the same network where IOU router is.
Now Microsoft Windows must configured with a Loopback adapter: add new hardware devices selecting “Microsoft” as vendor and “Microsoft Loopback Adapter” (Windows XP/7) or “Microsoft KM-TEST Loopback Adapter” (Windows 8).
Open Network Connections and select both VMnet1 and Loopback Adapter: right click and make a bridge. Host IP address is lost, so must be configured if needed (using the Bridge adapter).
Router-GNS3#ping 192.168.245.129 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 192.168.245.129, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 8/20/40 ms
And CDP is working also:
