Cisco 2620 Routers

dps

Hello everyone..

This site helped me a lot in getting info about the CCNA exams. Well, I'm currently reviewing for the CCNA exam and I was planning to purchase 2 2620 routers. They're selling the 2 routers for $250 including 2 WICs (T1 DSU/CSU). My question is.. can you do "back-to-back" connection with the 2 WICs? Or do I have to purchase serial WIC-1T's to do the back to back connection?

Thanks in advance.

If you have 2 wic Cards then you can do back to back. You will need a DTC/DCE cable. the router that has the DCE end plugged into it will just need to provide the clocking.

I'm pretty sure you can use WIC-1 csu/dsu for back to back connections. The bad thing is, it will be expensive to build a frame-relay switch with multiple T1 interfaces.

For CCNA, i think 2 2620's is kinda overkill. I have 1 2620 that I use for inter-vlan routing and as a frame-switch with a NM-4a/s. You can use a 2610 for inter-vlan routing if you have the right IOS and a fastethernet port.

Sorry i didn't read exactly what you wrote. I though you had WIC 1T cars.

from what i've seen fast ethernet cards are pretty expensive, so going for the 2620 is pretty much your best option.

I've never done it before - but you should be able to go back to back with 2 WICs with integrated DSUs by using a crossover T-1 cable.

It's a standard UTP, RJ-45 connector cable - using 1,2,4,5.

Standard Ethernet uses 1,2,3,6.

if you do choose the T1 cards then you would need to make T1 cross-over cables.

You think so? Should I just get one 2620 and purchase a 2610 to do inter-vlan routing? What IOS should the 2610 should be? The 2620 runs on 12.1 IOS.

Well, I plan on having 2 routers and a switch (prolly a 2950) for my lab. Will this suffice for the CCNA?

Thanks for all the replies!

Try getting 1 2620 and 1 2610. The 2620 is great for inter-vlan routing because it has a built in fa0/0 port and you don;t have to worry about buying a fa module for a 2610. If you want to practice frame-relay, you will probably want the WIC-1T cards.

In my earlier post about using a 2610 for inter-vlan routing, I was just giving you options. You don;t have to buy 2 expensive routers. With the modular routers, you have lots of different options but some are more costly than others. Darth brought up a good point, in that it would be more costly and time consuming to build a 2610 for intervlan routing when you could pick up a 1 2620 with everything needed for intervlan routing. But on the other hand, if you found a 2610 with a fastE port already on it with the latest IOS FOR A GOOD DEAL, then that would be even better. All i'm saying is make sure you get something for intervlan routing, but it doesn;t have to be 2 2620's.

But I do think that a good CCNA lab should facilitate intervlan routing, vtp, frame-relay, STP.

Thanks for the very enlightening post, man.
Will try to set up everthing this month so good luck to me. :P
Guess I will have to ditch the other 2620 and look for a 2610 with an fE port.
Time to surf Ebay.

If you get a 2620 with a built in fastEthernet port, then you really don't have to spend more money on a 2610 w/ a Fastethernet module. If the 2620 comes with one built in, you don't need another router with a FA port. Not for the CCNA anyways. You only need 1 router to perform intervlan routing. So just try looking at a 2620 for intervlan routing and a 2610 as another router to make serial connections. Try to stay with the Wic 1T because they offer cheaper scalability. Especially if you are going to buy a router down the road as a frame-relay switch.

Sorry if I confused you.

Good luck man!

Don't all 2620s come with a built in FastEthernet port?

Netstudent

I believe so..yes...the 2620's I have seen did anyways.
