Yet Another Home Lab Question

getting a lab setup for my studies, so ive been reading any and everything i could find about suggestions for equipment. To start im going to grab 2 Routers and a Switch.
Ive pretty much narrowed it down to 2 2620's and a 2924..Opinions much appreciated on those decisions..

My questions is i see the 2620's with a memory config of 32/8, 64/16, and 64/32..The price difference between the lower and upper one is roughly 75$ or so from what i can find.. What i want to know is what are all the benefits of running the higher memory config??

Apologies for yet another boring home lab question

No feature set on 25xx series routers will support IEEE 802.1Q. You can route between vlans yes, but you have to have 2 ethernet ports attached to each port on a switch placed in a different vlan (or native vlan id)

If i was you, i'd try to get enterprise basic for 2600's. c2600-j1s3-mz.123-22.bin (or w/e) As for routing and switching goes, ent basic will cover 95% of all required topics on CCIE R&S.

for security, like i said you need ik9o3s3

Hell, I'm just looking to pass my NA for now.

I found this...

http://cgi.ebay.com/32MB-DRAM-Memory-MEM2600-32D-for-Cisco-2600-2610-2611_W0QQitemZ290139255935QQcmdZViewItem

Good price? Is that what I should expect to pay for RAM upgrades?

Open up your router and check to see if its got 2 sticks of DRAM, if so then you have 2x16MB, your going to need 2x32MB and if i remember correctly the 2610-2613 has only 1 flash slot so you need 1 MEM2600-16FS (unless you plan to boot from tftp if you want to save money)

Nah, trying to keep this thing as least confusing as possible. Will open her up and let you know what I find.

Ok, just realised I'd have to remove it from the rack and then remove the brackets as well...

Way too lazy to do that right now. Will wait until I hit inter-VLAN routing to worry about it.

Alright guys. I'm very sorry for all of the questions. I just booted up my other 2610 and this is what I have on this machine...

Ok, this is confusing the crap out of me because I see 64 in some places but then at the bottom 32. I also see 4 for the flash in some places but then at the bottom 16. Also, with regards to this IOS, should I use this one for inter-vlan routing over the other 2612 I have? Ugh, i hate this.

Yeah, you're right. I read it a while back but obviously didn't take it in.

What type of serial cards do i need to purchase in order for me to run a small lab? There are so many cards avalible, and I am not sure which one/type i need. The Cisco book just states - "serial cabling Uses a DTE and a DCE cable"

Well, basically as the book says, there is a cable which is specifically labelled DCE at one end (to provide clocking and simulate a TELCO) and DTE at the other end (to simulate the premise)...

For lab purposes (and maybe other purposes), to simulate many of the scenarios required for many of the CCNA exams, these cables are required...basically a DB60 to DB60 DCE/DTE cable...

Thank you for your assistence, but what are the interface cards do i need to perchase?

WIC-1T, I thought those had the RJ-48 female jacks?

Netstudent

Well if you are talking about RJ-45, then no that is a UTP cable connector. These are cards for a V.35 DB60 serial DTE/DCE cable. Try doing some research on the internet.

I want to mount 3x 2620 routers and 2x 2950 switches in a rack. Do i want a 2 post or 4 post rack?

lex0429

i have a couple of 1760's laying around each with a T1 DSU/CSU module...any reason these are no good to use also?

im assuming i can setup a wan link between the two of them using a crossover cable, correct?

You need a T-1 crossover, not an Ethernt crossover cable.

lex0429

yep, got that..
does someone have a link to a tutorial about configuring 2 routers to simulate a wan link using the DSU/CSU cards and the T1 crossover cable? Everything i can find involves using a back to back cable.

r_durant

Check out this link and you can follow the threads, but in the end the guy had the cable made up wrong and the config did work...
