Consists of the following

1x 7507
1x 7206
4x 2821s
1x 3640
3x 2610s
2x 3560s
1x 3750
1x 355012G
2x 2950s
1x Pix 525 ver7
1x 1900

All this, contributes to no life, 30-40 hours of study a week, hair falling out, broken keyboards, weight loss/gain, funny eyesight... apart from that I love it

And thats just cheating!

what are all the routers in a cisco lab used for? i thought routers are only used to connect 2 different networks together, like WAN and LAN together, if at home you only have 1 ISP, connected to 1 of them cisco routers, what do you use the other routers for that are part of the lab? do you just connect one router to WAN and LAN switch, and the rest simply connected to the LAN switch on its own?

Routers are primarily used to connect dissimilar network topologies and allow communication between them, yes in there simplist form they can act as a gateway between a Wan and a Lan a good example would be your internet connection to your home.

But the router residing at your house simply acts as an endpoint to a much larger network.

Without routers, routing protocols and routed protocols the internet as we know it would not exist nor would many large organisational networks.

Have a look at the following to show the path a data packet travels to between two hosts, each hop is a router on the internet. Notice that the packet times out when it hits the firewall at the otherend as the protocol being used ICMP would be blocked by default.

TraceRoute to 83.245.33.202 [overclockers.co.uk]

I know these 2 routers intimately, I oversaw the installation and upgrade them often

No, in the london1 gateway near Aldgate.

i have a quick question about cisco labs, since i plan to do a ccna course (although the course doesnt actuly give me a ccna certification) as part of my degree in ICT in a year or 2 (long way away now, but my question should still be relevent).

what are all the routers in a cisco lab used for? i thought routers are only used to connect 2 different networks together, like WAN and LAN together, if at home you only have 1 ISP, connected to 1 of them cisco routers, what do you use the other routers for that are part of the lab? do you just connect one router to WAN and LAN switch, and the rest simply connected to the LAN switch on its own?

routers exist to make L2 broadcast domains as small as humanely possible, nothing good ever comes out of spanning tree

but mainly routers exist to agregate traffic and increase resilience (you just can't get the same failure protection at l2 as you can with l3 traffic)

the 'router' most people have at home is better called a home gateway, as it's a very different league

Sounds like some very interesting work.

Nice...however I will one-up you on Friday when I go back to our lab session.....we have a brand new suite of 40PCs w/dual Gbit LANs and 2 full racks of toys

Totally off topic, but what happened to your uploader? Will it be back soon? Was really good!

Possibly. I have much less bandwidth available at the moment, and it used quite a bit. But apart from that there's a few other things....we'll see over the next week or so

I should have mine built over the weekend. I have all the kit now and got a nice 12U cabinet to keep it all in.

pictures will follow ...............

All well so far but ive run out of wall sockets...which could be a problem, i have still got a sneeky bit of space for a 3600 though
