Cable modem config question

OK so my ISP (TW) is using Docsis 1 but plans to go to Docsis 3 in the new few months. I want to use my cisco 1721 is my head end router and connect everything to it. I do have a static IP if that makes a big difference. I want to know if A: Anyone is doing anything like this? B:If i should get something like a hwic cable d3 or something...

yes I have googled lol.

Edit: Mike, How does that module work?

You get a new gigabit port on the router when you install the switch module -- and then use that with the service-module command to access the switch.

Oh, look at the fine print regarding the 2900 series router...

If you can afford a 2900 series router you can afford the adapter -- or real 3750 switches

Total $602

And what's the price with 2 of those bad boys in a 3725? How does that compare to 2 3750s or 2 cheaper 8 port 3560s?

Hey -- don't run up the prices. I'll still probably add another one to my 3745 someday.....

Looks like that adapter goes for about $200 on ebay.

Either way, the combination of the router, module and adapter is still much cheaper than just the 3750!!!!

I'm interested in this for PVLAN purposes and fast-etherchannel, at least I hope fastetherchannel is possible...

I thought we had another discussion about the switch modules somewhere, but I can't find it right now.

Here we go -- one over in the CCIE Forum....
http://www.techexams.net/forums/ccie/48181-nme-switch-module-vs-3750-a.html

And pitviper mentioned the NME-16ES modules again in a CCNA:Voice post....

But yeah, 3560s are really nice - I'm going to snag one after I'm done with the CCVP but for now 3550s and an NME-16ES-1G-P w/3750 IP services IOS are just fine

.... but luckily no one noticed and drove up the prices before I got mine

The 2900 & 3900 routers that need that adapter are the NEW ISR2 routers.... exactly how cheap are you finding them on eBay?

So do you use one for uploading/downloading or are you doing something else entirely?

Bonded 25/2 meg cable modems. I effectively have 50 megs download and 4 megs up. I could probably call some buddies at cox to get my upload increased but that would just be greedy. I'm using pfSense because it will load balance by default with almost no configuration. I could theoretically expand my setup to 4 total modems (I have two more modems and the required ports on my firewall) but don't feel like running two more drops from the pedestal and I also don't need that much bandwidth. I've got a dedicated server with unlimited disk space and bandwidth hosted at a colo so not necessary.

ohhhhh!!! My bad, I looked it up wrong, got a little dyslexic there with the model numbers.....

See if Cox will run BGP with you.

I had a full BGP feed off my ISP at one point but got them to turn it off because it was hammering my DSL. If FTTC comes out in my area then maybe I'll get it turned back on...

Would this not be an excellent way to learn BGP without messing up any production networks?

Better to mess up the internet instead? Hahaha. (Though this shouldn't be possible if the SP isn't retarded)

Tiersten, how did you talk them into running BGP on a residential circuit? I'm assuming you were using a private AS and don't own one yourself... right? It'd be pretty damn cool if you had one, and some of your own space though, lol.

I don't have any hardware that would support a full routing table. I'd have to build a linux router to come close. I've thought about it.

It was just a private AS off their Quagga box. The ISP I use is actually pretty technical orientated and will let you configure most things or configure it on your behalf. They offer things like native IPv6 over DSL.

I've got a netblock allocated to myself but as I'm not multihomed I can't get a real public AS number.

ARIN will let you get an AS number if you aren't multihomed, you just have to explain your "special routing needs". It's even easier to pry an AS number out if you use a 32-bit ASN.

Yeah but the easiest way is to be multihomed

Also I'd need to get it from RIPE NCC and not ARIN.

"Because I want to play around with BGP" is probably not sufficient!
