Building Some Olives

MrPaul

I've just failed my first attempt at the CCIE SP lab and the next open date is August 2...only 7 months. Sad thing is I passed the lab but failed the core knowledge so if I took the test 30 days ago it would be a pass.

Anyway, I've got some down time and considering jumping on the Juniper track. I've spent the better part of the last 2 days building a couple olives on my lab server (Ubuntu) that was running dynamips.

I've established connectivity between two olives using the guide at the GNS3 site but I'm looking for a little more flexibility. What I would like is to have em0 all connected to a virtual switch (or hub). My goal is to simply build VLANs on the em0.xx interfaces as needed to establish my broadcast domains and I want to be able to configure them on the fly.

I've not had much success with this. As soon as I add the vlan-id to the unit I'm no longer able to ping between the two routers.

Some of the setups that I've tried are as follows. Each of these works without vlan tagging but I no longer see ARP reply's in the tcpdump output after adding vlans.
- br0 with tap0 & tap1
- dynamips "ETHSW" bound to tap0 and tap1
- dynamips "ETHSW" bound to UDP ports
-- this wouldn't even start

Is this an option? If not is there a way to build 12 or so olives with networking inside qemu?

There are only a few guys who work with olives in this forum... and I am not sure how much they might be help... I suggest you to post this question "juniper-nsp@puck.nether.net" a forum just like the CCIE group study... I have seen some guys build some really cool things with Olives in those forums...

But yeah go for the JNCIE-M... but you do realize that it is JNCIP first and then onto JNCIE.. so two labs in this format...

I can definitely help out with configuration/case studies etc over here... Not much of a olive expert though...

Cheers,
Hoogen

You can connect olive to a cisco NM-16ESW in dynamips with udp tunnels like this (I used for testing only one olive and 2 cisco routers in dynamips)
