[zebra 23004] Re: BFD implementation with zebra

That's cool !

It seems that the patch for zebra is very clean code.

Is it that the kbfd notices the zebra by netlink (or interface flag
changes) and the zebra distributes the event to the protocol daemons ?

I'm also wondering if it has interoperability with any vendor's BFD.

regards,
yasu
