Voice Lab – Frame-Relay WAN
Posted by Josh on Wed 3 Dec 2008Categories: CCIE , Cisco , Cisco Routers , Cisco VOIP , GNS3 , Voice LAB - [19] Comments
This is the Frame-Relay WAN section of the Virtual Voice Lab. In this tutorial, you will learn how to connect Branch 1 and Branch 2 routers to the Headquarters router using frame-relay PVCs.
If you have completed all video tutorials to this point, you should have a functional Call-Manager Server, IPBlue Softphones, three branch routers and frame-relay connectivity between the branches.
- Add a WIC-2T card to the Headquarters router
- Add a Frame-Relay switch
- Configure PVC mappings between the HQ router and both branches.
- Add routers for Branch 1 and Branch 2
- Add an NM-16ESW module and a WIC-2T card to both branch routers
- Connect all routers to the frame-relay switch
- Configure the routers for Frame-relay connectivity between the branches

thnx for the tuts…

Thank you very much for this tutorial and all the others, too!
I think there is a little typo in the configuration here. On the HQ router, the IP address for S0/0.2 should be 10.254.254.5, not 10.254.254.2, because that would be on the same subnet as the address for S0/0.1 and it is needed on router Branch1.

Robert,
Thanks for catching the typo! My proof reader will be fired today

Khalid,
Yes, you should be able to use a 2600XM image.

Hi Josh,
Thanks for that. I’ve built my lab using Dynamips rather than GNS3 (although I do have a lot of the hardware as well). I’m using the same version of IOS on all three routers which is c3725-ipvoice_ivs-mz.124-15.T7.bin. This is the only IOS for the 3725 that I could get hold of that supports H323 and I didn’t want to run different types of routers. However, I find that when I run three routers, despite using the best idlepc value, the CPU is at well over 90% for most of the time. Add the VMWare sessions for CCM/IPCC and Unity plus 4 IP blue phones and we’re very close to 100% CPU. Any ideas on how to improve this? I’ve used BES but if I reduce the Dynamips CPU utilisation much, I find that when I’m entering commands in IOS, the IOS is slow to keep up with my typing.

Josh plz tel me da IOS name.. i was tried so many but.. they not working fine.. plz…
@AK
well frndz em also…

@khalid
i m using
c3725-adventerprisek9-mz[1].124-15.T5 ios… and i m gng fi9 with it…

ciscoguy,
Here is what I do to get a “good” idlepc value.
Start a lab with a particular IOS image. Watch the task manager while you test different idlepc values.
You may have to try several different values before you find one that works well.
Once you find an idlepc value that works, build your lab with the IOS image/idlepc combo.

Hi Josh,
That is exactly what I did but none of the idlepc values are any better than what I’ve already got. Might be to do with my version of IOS. Thanks anyway mate.

Ciscoguy,
Yeah … now that you mention it, I have had to change IOS images before. Try that and post back.

Hi Josh,
Thanks for such valuable tutorials; my virtual lab is ready with FR cloud and now waiting for more.
Thanks, Shahid

Hi Josh
Can you please post the FRAME RELAY Configuration, i have the real equipment to test.
