Sample lab topology/configurations

techster79

Hi,

I'm studying for the CCNP(currently BSCI). I have the exam certification books, and running dynamips for my lab. I'm trying to master EIGRP/OSPF now before moving onto IS-IS, multicast, IPv6, etc. Does anyone have a good lab setup/config that is handy for studying these topics? I have a X2 5200+ with 2GB of ram and can run around 8-12 routers before it starts crawling. I need more memory to push it up to 15 or so, but I digress...

Get the BSCI self study guide it has a really good lab topology in it and lab exercises at the end of each chapter.

when I was working on the BSCI, I setup 4 routers in one big loop. Then picked on one to watch the routing table with different ospf area types as well as eigrp path selections. Nothing too specific, but watched debugs, routing table, and adjacency tables.

Hey pea brain

maybe you would be interested in the lab portfolios that are supposed to be the new lab companion guides.

They come out Jan8th. I know i'll picking them up.

Thats it? Can the BSCI really be adequately studied for with only 4 routers?

No frame relay configuration? How did you study all the OSPF topologies? The only way path selections would change is to tweak the K values or change bandwidth. I saw an example in one of the EIGRP chapters of routers rung together in a pentagon style with a fast, longer path over the top and a shorter, slower path on the bottom. Is there anyway I can upload and post an image of the configs I use?

You could do it with four routers. You would have to use a lot of loopbacks to create more networks and areas. I have nine routers (one as frame switch). I usually only set up about four of them when doing labs though. I'm doing BGP now which is fun to use all the routers and have differnt ASs with differnt IGPs running. Its better to have more routers, but four would be doable for sure.
