What to buy next?

in CCNA & CCENT
Hmm...guess polls are disabled in the forum. I know this is in the FAQ but there are so many answers and I can't decide which one to go with.
Part 1: I just recieved my 2612 today (woo-hoo). It has 1 ether, 1 token, console, and aux. I have 2 WIC-1T's on the way. Only needed one for this router but got a good deal and figured I'd need more in the future anyway.
Part 2: I just won an auction for a 12 port 2950 switch and expect to have that sometime next week. Obviously that'll either be coming out of my token port or ether port on my 2612.
Part 3: And this is where I'd like some opinions. I can't for the life of me decide on which router to get for the 2nd one, and probably last one until after I pass the CCNA. I might buy another switch to complete the set but want the router first for now. So which do I go with? I was just going to get another 2612 but who the hell needs two token ring routers.
I looked in the FAQ and see so many options ranging from 25xx's up to 26xx's. Do I get a 2610, 2611, 2612, 2613??? I want this to be scalable as well. I noted on the cisco blueprint the 2610's could be substituted for some of the more expensive equipment. Should I get a router with BRI interfaces so that I can practice ISDN? Is that practicle since ISDN is not as hot?
Just looking for opinions. And a bit of boredom as well. Sitting in at home on a Friday night doesnt help.

But yourself a terminal server either a 2511 or a 2509 , the 2511 has 16 lines wheras the 2509 has 8 lines.This router has 2 serial interfaces, 1 ethernet al built-in so you can use it both as a terminal server and a router.Networking, sometimes i love it, mostly i hate it.Its all about the $$$$ -

Hmmm...never tried that before. Does it hurt? :P
Sorry Ed. Friday night boredom drives me nuts. Well crap. What am I going to do with the extra WIC I have coming in? Hey, if the 2511 or 2509 come with 2 serial interfaces, couldn't I just place the 2 WIC's I have coming in into my 2612 and create redundant serial links between my routers? I know this would have a purpose in regards to my studies but I forget what it is. STP is for redundant switch links.

Aha, good call.
Yo this 2511 is an expensive sucker. I figure the 25xx series would be cheaper than the 2600's. Damn. Around what should I pay for a 2509 or 2511? I'm seeing around $150-$200 on ebay for the 2511's."You, me, or nobody is gonna hit as hard as life. But it ain't how hard you hit; it's about how hard you can get hit, and keep moving forward.

eh i'll take a 2511 if he's selling one :-p..i think i have more equipment than the OP.. trust me its not fun switching one console cable between all this crap.(now 1 2620, 1 2514, 2 2501, 2 2504, 1 2520, 3 2924s, and 1 2912...).. Also, if you're interested, i've found a seller that is selling quite a few 2600 routers if you're wanting to pick more up. I just bought a 2620 32/8 for $109 +ship ($15)... he's got another 2620 for $100 as well, 24/8. Add a couple serial cards (cheap) and spend like $60 on some memory and you're cake. Oh, he's got 2611s & 2610s at around $150 or less also. I also think my 1912 from cisco kits came with a newer IOS for the 2600s, so that helps me. now i just need to find myself a 2950.. i guess i'll wait til next month when i get my bonus.Fantastic.

Hey Mark,
I would also get a 4 or 8 port serial card for that 2600 and then you can use that 2600 as a frame switch. -

Definitely don't get a 2613. You'll only have 1 Token ring port,
and will not be able to add a enet port.
You could get 2511. $200 is a fair deal.
You could also use it as a frame switch when you add
the second router as it has 2 serials.
Practicing ISDN? That's kewl. you won't need it for
an exam, but a lot of people use it as a back up
in the real world.Lab first, ask questions later -

DM, are you talking about the smaller serial interfaces I've seen. I think they're called WIC-2T? I don't think I've ever seen 4 or 8 serial interfaces on a single module/card.
Seraphus, looks like you're also saying I should make one the frame switch. Would I need only 2 serials on a router or the 4-8 that DM mentioned? I'm thinking I might be leaning toward a 2509/2511. As someone mentioned...switching the console cable all the time would be a pain in the ass.
And rather than create a whole new thread (which you all know I love to do) a question just popped up. I'd like to try and simulate a real environment in my home lab. I don't want to have just one host coming off of my switch. I want it to seem like an office environment with lets say 7-8 hosts/switch. BUT, I don't want to buy 7-8 PC's. I asked my brother earlier today but he didnt know...can you put like 4-5 NIC's into a barebones PC and treat each NIC as if it was a seperate host with seperate IP addresses? If that was possible I'd be able to configure a much more detailed lab.
EDIT: Hey Mike...sell me one. "You, me, or nobody is gonna hit as hard as life. But it ain't how hard you hit; it's about how hard you can get hit, and keep moving forward. How much you can take, and keep moving forward. That's how winning is done!" - Rocky -

Yep, you can install an application called virtual server or virtual machine, cant remember exactly maybe their 2 different apps that do the same thing.I'm looking at doing this when i have some time on my hands. I dont know the limit but you can definitely manage 4 Pcs on a machine, probably need alot of ram processor etc i have a dual core with 4 Gb so its not really a concern.Networking, sometimes i love it, mostly i hate it.Its all about the $$$$ -

You can make the 2511 a frame switch, as well as use it for OOB management
for your other devices. I'd only do this if your gonna' stop at 2 routers (in addition
to the 2511) just to review the technology itself. Or you can make that 2612 with
2 WIC-1Ts a frame switch to the 2511 and whatever else you get. But this is limiting.
If you plan on going for the CCNP, (again... and I feel your pain
) I
highly recommend getting a 2511. You'll thank yourself immediately, and then
again later.Lab first, ask questions later -

Oh, hmm, that sounds like it'd be more expensive than just buying 4 NICs and finding a motherboard with enough slots for them. I'd have to go out and get a powerful machine like the one you've got.

I hear ya; though you may wanna' grab one of those too if you
decide to expand.
I think that 2511 is well worth it; I should know, I bought one several months
ago when one popped for $169.00 w/ cables $30 shipping. Look at like this:
it will probably retain its value by the time you complete your NP. (Assuming
you complete yours within the next rolling year, of course).Lab first, ask questions later -

So I'll repost with more information for you...

NM-16A/S 16-PORT ASYNCHRONOUS/SYNCHRONOUS NETWORK MODULE
Asynchronous/Synchronous interfaces are the most versatile serial connections that Cisco offers. These interfaces support a wide variety of protocols and applications, including WAN concentration, transport of SDLC and Bi-sync data, and asynchronous terminal connections. Cisco announces the availability of the NM-16A/S that has double the interface density of the NM-8A/S.
I think you misunderstood me. I wasn't looking for a module with serial interfaces."You, me, or nobody is gonna hit as hard as life. But it ain't how hard you hit; it's about how hard you can get hit, and keep moving forward. How much you can take, and keep moving forward. That's how winning is done!" - Rocky
