Voice Lab - Headquarters build
Posted by Josh under CCIE , Cisco , Cisco VOIP , Dynamips , GNS3 , Voice LAB -I just finished the video tutorial for the headquarters part of the virtual voice lab. This tutorial will basically walk you through adding all the devices for the headquarters location.
Update (12/19/2008): The steps below only partially work. I ran into issues communicating with the host Ubuntu Machine. When you are finished with this tutorial, take a look at this one: Linux Bridging for GNS3 LAN communications
Here are the basic steps:
- Open GNS3 as root (this is necessary for bridging to the LAN)
- Add a cloud icon bridging to eth0
- Add an ethernet switch icon for Headquarters
- Add two decorative nodes (computers) to represent the Call Manager and XP workstation
- Add a router icon. I am using a 3725.
- Connect the ethernet switch to all other icons.
- Configure the router with an IP address and ping the Call Manager to make sure the bridge is working.

I know what he means I used to check this site all the time. Love the updates I have successfully installed CCM & Unity with their help. What version of linux are you running? I currently have Ubuntu Server with no GUI so I think I will need to add this to use GNS3.

hi JOSH,
I have configured extension mobility service on ccm413. but when i click services button on IP blue phone. it gives me following message.
“An ActiveX control on this page might be unsafe to interact with other part of the page. do you want to allow interaction ?”
When i click yes. it doesn’t show me the “extension mobility service (Login)”. any idea abt it ?
Regards

Hi josh,
Thank you for this tutorial, but i still have some problem to mount my virtual voice lab with GNS3 VMware Server on ubuntu.
My CUCM is connected to VMNET3 who is configured with host-only on vmware.
In GNS3 i follow your step, and i connected my cloud to the vmnet3 but i can’t ping between the router and the interface vmnet3.
My config miss any thing????
Thank you

Naoufal,
There are several things that could be wrong here.
Are all interfaces up on the router?
Is the firewall on the Linux server allowing pings?

Josh,
Thank you for the reply.
I don’t have any firewall on my ubuntu, and all interfaces on the router are UP.
I remarked that i can’t bridge any interface with GNS3, i tried eth0, and nothing.
Thank you

I can ping between the virtualMachine and my laptop, but the problem reside on GNS3

Naoufal,
Are you running gns3 as root?

Josh
Are you running CCM along with HQ-BR1-BR2 all on the same laptop?
Or you have CCM on one machine and HQ-BR1-BR2 on a different machine.
Thanks in advance

AK,
Yes, I am running them all on the same machine. The goal is create the best lab possible with a single PC … and maybe a router.
Although all virtual devices are on the same physical machine, I only activate the routers, vmware servers that are needed for specific tests.

Things have been very busy for me lately, but I do hope to have h323, sip and/or mgcp tutorials in the future.
