Linux Ethernet Bridging - Aug 2009 - [Bridge] bridge on colinux: need to configure bridging in kernel

Hi:

I'm trying to setup dynamips to simulate some cisco routers in ubuntu and I
need to bridge the router interface out of the linux NIC (so two virtual
routers hold by 2 linux can talk), and it looks I need this fancy bridge
tool, but.

When I install the bridge-utils and start to configure a bridge, it reports
the following error:

# brctl addbr br0

add bridge failed: Package not installed

 

read through the document and realize I probably need to "configure
Ethernet
bridging into my kernel", here is my kernel version:

root at ubuntu-1:/home/ping1# uname -r

2.6.22.18-co-0.7.4

 

So , yes I'm using colinux (running on top of winxp), but I don't think
that
should be the root cause, problem is now how do I "configure Ethernet
bridging into my kernel"? 

Sorry this may sound a stupid question for experts but I'm not an export of
linux so that sound real hard and dangrious for me , any step-by-step
suggestion on that?

 

Thanks!

 

Regards/ping

If bridging is not in the kernel, you will have to reconfigure and
recompile the kernel. If you don't have source and/or tools to do
that, there is no other clean solution.
