IP Telephony first steps with Packet Tracer

Hi all,

I'm so bored today... that I started moving my first steps into the magic wonders of IP Telephony! :-)

The only tool I have at the moment is the great Packet Tracer, as I'm a Networking Academy instructor and Alumni.

Well, I have to admit that I'm completely a newbie on IP Telephony, so like every CCNA, I started using Packet Tracer to simulate a simple multisite CME installation.

Here is the result:

You can download the Packet Tracer topology file Here, the topology is already configured and ready to play with.

The relevant topics I have learned with this small lab are:
-the use of option 150 in DHCP for IP Phones
-the basic dial peer configuration for multisite CME

Have fun

World IPv6 day: looking for results

Hi all,

as network engineer I'm excited to see results and analisys of the yesterday's World IPv6 Day.

First of all, like a technician does, I looked at the graphs provided by Arbor Networks. Seems that the IPv6 traffic has been increased yesterday, reaching the 0.04% of all internet traffic, according to their measurements points. (Is this data exciting? Need to search more in depth!)

Another source of informations and graphs is the RIPE NCC World IPv6 Day Measurements Page.

The participants have added AAAA DNS entries for their main sites, increasing mainly the NATIVE portion of IPv6 traffic, that's a good thing...

I look forward to see the updated Google IPv6 statistics, just to have an idea of the real impact on a single organization...

Facebook declares the results HERE, but without providing much data or graphs.

I personally hope to see all the participants with permanent AAAA records, but also to see my home ISP start supporting IPv6 ...

cheers
Marco
