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

[Deon Vermeulen]

Hi Tommy, Giany, Stefan

I manage to find the problem.

I created a qemu base image with Junos 10.2R1.8, but instead of using the 182559er NIC I used the e1000 for my JUNOS Routers.
I reconfigured all interfaces for JUNOS Routers 1 to 4.
I got this error when committing my configs: 

!
root# commit 
Interrupt storm detected on "irq11:"; throttling interrupt source
!

I also got this error after all my configs where done and I started testing connectivity with pings:

!
root at R1# em2: watchdog timeout -- resetting
!

I googled the above error and found the solution to my problem on this page
http://www.gns3.net/phpBB/topic2147.html?sid=0a8b808d046a2697efc844a92cd1e45a


The problem seems to be with fxp3,em2,etc... So I just adjust my Router connectivity to not use Interface 2 and my LAB is working.

According to Nacho ( who posted 19:13, 28 April 2010 on http://blog.gns3.net/2009/10/olive-juniper/) IPv6 and multicast (PIM) is not supported on the e1000 but on the i82559er interfaces.

I have a MBPro with 4Gig RAM, so I'll be setting up my LAB with the 182559er interfaces and see if my qemu instance crashes when running the EBGP case study on my machine.


Kind Regards
