I am building a CCIE VOICE LAB at home and am trying to figure out how many 3750 Switches and how many routers are used in the lab. Also, what interfaces are required in the routers. Also, does anyone have a basic diagram of the Lab setup (as long as it doesn't violate the NDA). I would greatly appreciate any feedback on this.
this actually is a question which cannot just be answered with a list of hardware. Depending what topics you want to go into deep, you would need to reconfigure from time to time. As a general reference for a good start you could use this link:
...but this is a list after which you end up to be broke. Maybe you like to combine this with some VMware and GNS which is making the whole life more flexible and easier to add/change components. For my knowledge IOS V15 is not yet part of the lab, GNS can still do the job for a while.
For the servers/appliances I use a single motherboard on i5 basis with 16Gb RAM and a trunking capable ethernet card. Each VM has it's own disk partition(small, cheap disks 160GB for 30$ from newegg) so I/O is not a bottleneck. This way I can run 7-8 servers inclusive AD/LDAP-server etc on one box and still have every server on a different VLAN. I am running 2 VM-based servers per physical disk which is working out pretty nicely.
Same here, am running CUCM, UNITY Connection, Presence and soon UCCX on VMware. Use this guide:
Google knows where to get the CCIE Lab Visio
blindhog link is good start but it is old, I think it is based on previous version of CCIE Voice, isn't it?
In order to adequately prepare for the CCIE Voice lab, a single 3750 (or 3650, as it has the exact same CLI) will do, along with 4 routers (1 to emulate PSTN and a few others for main and branch sites), and basic voice T1/E1 interfaces.
