Cisco router question

Recommended Posts

Hey folx, I have a quick question. I am not a Cisco or even a network guy. I do servers, so excuse my ignorance if I sound like I don't know what I am talking about.

I am getting a pair of bonded T1s from my ISP. I have worked with individual Ts before but never bonded. I have a series 2500 and a series 4500 router that I can use (I don't care which). What do I need in the router, do I just need 2 T1 WICs or do I need some other kind of card?

Well for starters you can't put WIC cards into non-modular routers like the 2500, (but the Smithsonian might take it).;) I'd go with the 4500 because it is modular and you can actually get current images for it. I haven't actually set up a bonded pair but AFAIK you can bond any two similar serial links on the box. BTW there are WIC cards with dual T1's on a single card, which saves a slot.

How the heck is a server guy getting into such serious networking??? The server guys I deal with usually can't even grasp the difference between a switch and a router.[:/]

Edited to correct: The 4500 is not part of the modular router line.

I do quite a bit of the basic networking stuff, but this is above my skillset. I was next going to ask if anyone here wants to make a few bucks configuring this for me. It is a good client of mine that just ordered a new link without talking to me about it first and this is what he was talked into.

So I just want to make sure I understand this. I can treat the bonded T as 2 individual ones and just plug each into a T1 WIC?

Isn't a switch just a *really* fast router?

Walt



Switches do layer-2 forwarding based on MAC address.
Routers do layer-3 forwarding based on IP address.

The term "switching" get seriously over-used and abused by marketing 'droids.

And to make things even more blurry, many enterprise-class switches can also do routing, (sometimes referred to as "layer-3 switches").

Wow, very nice explanation--thanks!:)

and I still suck...[:/]
I swear someday soon I'll have a telephonic device and be able to once again converse with friends...I just hate to have to buy a cell phone...shudder....
you're going to need another device Oren...the 2500 isn't modular and will most likely only handle one T-1 - depending on the actual model and the 4500 is a switch. The backplane speed of the 2500 also is not capable of the bandwith of a full T much less 2 of them.
Try to locate a used 3600 series router at least...or maybe a 2800 even...but the WIC-2T will be the card you will want. Then they need to be bound in the configuration.

Actually i just realized that I didn't mean 4500. I don't have it in from of me but it is a 2U modular router not a switch. I just don't remember which model it is. Actually quite a while ago it is a unit that I was talking to you about selling it to someone that you worked with.

Do I have to use the WIC 2T. If I already have 2 seperate T1 WICs in it can I just use them?

that mey indeed be a 3600 maybe a 3640 if I remember correctly?
send me the name of the interface cards on it when you see it again if you would.

I'd be glad to help, being on the other side of the state and just starting a new contract may make that tough to do though....

I'm kinda surprised the telco is still selling T-1's too...:S

added - yes two seperate WIC-1's will also work fine.

OK, they are 3600 series, but I don't have the exact model at the moment. It doesn't really matter where you are since the client is in NY anyway. Did you see my question about using 2 seperate T1 WICs instead of the T2. Is that possible, because it already has 2 seperate T1 WICS in it.

1 more question, this office also has 2 DSL links 1 is 1.5Mbit and the other is 3Mbit. Is it possible to cennect these all together so we can load balance and or failover. If so, what else do I need?

The physical interfaces will look like:

interface Serial0/0
interface Serial0/1

The bonded virtual interface will look like:

interface Multilink1

This is on my 2610xm with (2) WIC-1T's.

yeah - but are they "dishwasher safe?" I think not! :P



Probably so. I doubt they would hurt the dishwasher even a little bit. Unless the dishwasher is a person and you throw the switch at them.

Walt


It is not nice to throw switches at anyone! They hurt! I caught a 6500-e chassis with my face while trying to rack it with my coworker. Warning, racking 6500's with out the lift and having tiny hands, you hand will get stuck in the handle, almost broke and you will be balancing the thing on your eyebrow.

That was my PSA for the day....
