Kernel protocol and different namespaces

[bird at ipv2.de]

I disagree. I am quite sure this is technologically possible. As in, the Linux kernel should allow you to do this.

I doubt bird is capable of this, as is, but it should be possible to patch it in order to do this.

For some simple testing on how to traverse network namespaces, you can use ip netns.

I was hoping I could just stick to one instance and export routes to different namespaces.
