[1.] One line summary of the problem:
I am using linux and quagga (latest release) for a small network. It
does load-balancing between 3 providers.
[2.] Full description of the problem/report:
If I only make a default route (the hard way - route add default gw
xxx.xxx.xxx.xxx) everything is more then OK, but AFAIK this is not the
way to handle routes in BGP. So I did registered the three gateways in
zebra as default routes. After a couple of minutes, the kernel oopses:
I have googled the problem and showed up only one article:
https://www.redhat.com/archives/fedora-test-list/2005-May/msg00373.html
Maybe, if we find out the problem, we can let the poor guy know ;)
[3.] Keywords (i.e., modules, networking, kernel):
kernel, networking
[4.] Kernel version (from /proc/version):
Linux version 2.6.13 ([email protected]) (gcc version 3.4.4) #1
