[j-nsp] Olive Qemu/GNS3 networking issue on Snow Leopard

[Stefan Fouant]

Why use Qemu/GNS3?  I prepared for JNCIP entirely using traditional Olives
in VMware Fusion on a Mac.  All you need to do is add a few additional
vmnets to the VMware configuration files and then modify each Olive's
individual configurations to map the E1000s NICs to specific vmnets.  Much,
much easier than Qemu/GNS3 IMO.

Hi Forum,

I have been trying to get the JNCIP LAB
(www.juniper.net/training/certification/JNCIP_studyguide.pdf) up and running
on my MacBook Pro running Snow Leopard 10.6.3.
I've manage to get it working with qemu using UNIX sockets and UDP tunnels,
but only 2 Juniper routers (R1 & R2) could network with each other.

After 5 months of back and forth I eventually got GNS3 running for Juniper
under Snow Leopard 10.6.3.
I manage to get the JNCIP LAB setup and start all routers just as with qemu,
but still experience the same networking issues.

I can only ping between R1 and R2.
I see the arp entry on R1 and R2 for R3 but can not ping to R3 from R1 or
R2.
On R3, I can ping the local address of the interface connecting to R1 and
R2, but cannot ping to R1 or R2 from R3.

I disabled my MAC Firewall, but still no luck.

My LAB Topology is based on the Official JNCIP Study Guide from Juniper.

Any help/guidance will really be appreciated.

Thank you in advance

Kind Regards
