Vito,

Its very hard to understand what you have going on there. You should describe what your doing, where are you redistribution points? are you running iBGP within AS5500 or are you letting OSPF take care care of the routing? Where are your eBGP peerings? Doing any kind of attribute mainpulation(MED, AS_PATH prepending, local pref?). Not bad to start though:D

Ive got two challenges for you though,

Challenge 1:
iBGP peer R4 and R3
iBGP peer R3 and R1
You cannot peer R1 and R5 via eBGP.
You cannot redistribute BGP into OSPF.
verify that R1 can ping routes being advertised from AS6500.

Challenge 2:
R7, R3 and R8 into EIGRP AS 200
configure R7 as a stub
configure loopbacks on R3 and advertise them into the AS
verify that R8 can ping the loopbacks on R3.

Post your solutions and "show" verifications.

Have fun bud, anyone else that wants to join in and do this... feel free. Maybe someone should re-resurrect the thread I created awhile ago. Also, look for a post from Null_0 soon, even though he is new here, he is easily the sharpest here at routing and switching.. :)

A lot of it is probably due to my lack of Visio skills. Yesterday was the first time I really tried to put some effort into learning it. That diagram is layered also, so it would probably be easier to understand if I didn't have all the layers visible, lol.

I'll work on the challenge you proposed.

R1 can ping routes from R5, but I didn't do it with through BGP. I couldn't figure out how to get them into R1's table through an iBGP peer with R3. I thought of two ways to do it that weren't explicitly forbidden in your challenge. The first would be to peer R1 with R4, the second would be to set R4 as R1's DG, which is what I did. I'm sure there is a way to do it with through R3, but I don't know how (second day playing with BGP, lol), please explain if you have time.

Im in CCIE mode now, so I forgot to stipulate, no use of static routes is permitted here. Also, for both solutions use the "best"(ie. cisco) solution.

For challenge 1:
You must use BGP.
You cannot peer R1 and R4.
If you need a hint, look at why its an unwritten requirement for iBGP to be fully meshed and if its not the solution.

For challenge 2:
Your output for the ping is from R7, not R8. Your solution would work, but Im going to make a few stipulations as this is not the "correct" answer.
I want to be able to ping R3's e0/1 interface from R8
I want to be able to ping R3's loopback addresses that are:
1.1.1.3
12.1.1.3
12.2.4.3
I want specific routes in R8's routing table, no static routes and obviously no summeries.
 
The output was from R8, I use the router models as hostnames (R8 is 2620xm), I changed the prompt when I posted it in to make it easier to read, the R7 was just a typo.

I'll go back through and redo everything. Still don't think I know how to do the BGP one.
 
Hey Vito,

You might want to look at http://www.cisco.com/en/US/docs/ios/iproute/configuration/guide/12_4/irp_12_4_book.html. The answer is definitely on the page. Also, I work with Xphile and there are key technologies he is looking for you to know, which will be very beneficial for a BSCI student as well as a potential CCIE candidate. I am also planning on posting some other challenges based on your NICE diagram.


from xphil3:

Vito,
resurrect the old challenge thread that i created and post your diagram there. We can all begin to propose challenges to anyone that wants to participate. Also, if you can build out this topology in dynamips and include the netfile.
 
Versello, that is an awesome setup.
Could you guys put that network info in a separate thread. This is a photo gallery not a general chat thread.

Here are some switches I've picked up...need to cut some vent holes in that rack, it's for studio equipment or whatever.

I always hated those purple beasts. We had one at my college. At one point, ssh would no longer work even though it was setup correctly. Three technicians from the company came in and had no idea why it wasn't working. Then, a few months later, it randomly died, which turned out to be a good thing.

Replaced it with a cisco 3750 gig stack, smooth sailing ever since. I hope you have better luck than me.

Extreme Networks make top notch equipment, I've used dozens of them with great success.
 
Here is my current CCNP / CCVP setup. (always changing)

S1 - 3550 POE
S2 - 2950G
BB1 - 2514
R1 - 2610XM
R2 - 2651XM
R3 - 2821

I have another 3550 POE on the way, and CUCM7 in VMWare not shown here. I also have all routers, switches, and vmware hosts setup on an interactive web interface similar to NetLab so I can use all equipment from anywhere on the Internet. Only thing I cannot do remotely is use the physical phones, but all hosts have IP Communicator.

Junk! :eek:

Best DSL modem I've ever owned - my original got killed by lightning a few months back, and it seemed impossible to get another one in the UK. One turned up on eBay eventually, but the junk I had to use inbetween was unbelievable. Maybe you guys have a better choice of ethernet DSL modem over there.

Since I'm posting, here's an image that I've probably posted before:
Chrixnet.jpg


It's a bit out of date as I now have a second 24 port patch and the switch is full, but:
Switch: Linksys SRW224
Black 2U: Ubuntu web/ftp/mysql/usenet/nagios/thermd services
Left tower: IPCop (need to replace this with something smaller/quieter)
Right tower: SBS 2003, Exchange and AD (smaller/quieter needed again)

Here's a shot taken from Nagios (live on my status page http://thefnet.co.uk)


The topology is not strictly correct, but close enough. :)

playing around with them, the extreme switches do routing so I set up various configurations and test them out, got the HP mainly to become comfortable with how they operate. I didn't buy them because they this or that many ports hah but if I ever want to host a huge LAN I'm good haha. :D

Here's my contribution in visio right now. At least until we get the esx lab built.

It's was a simple setup turned full fledged deal.
Everything here except how the esx is setup

We are going to use iSCSI for storage. This is what is left out for connections in the first diagram. Not sure if we really have the redundant part covered :p

Just picked up a couple of Cisco 3524 XL's One is already in use so I decided to get a pic of the one not in use...

btw if you are ever looking for Cisco stuff, look up NetworkHardwareSupply, one of the coolest and nicest ebay sellers you will ever meet, and usually has some incredible deals.

Err were did you see a 3550-48??

The switch is a 3548 he had and was installed for a relative who asked for his help in setting up a lan.

Doesn't hurt to ask before you post such a comment
