Re: Multihop BFD support on OpenBSD

Hi :Peter,
Thanks for the update.
I agree that portable version doesn't make sense here.

Hi,

You may have noticed that our BFD implementation is not enabled, and
that is because it is not yet finished.

Multi-hop support is one of the things that is on a TODO list, but there
is no intention on working on that feature in the near future.
Additionally, there is no intention of making a portable version of this.
It is primarily a kernel implementation, so a portable version wouldn't
make sense.

: 1. Is there a plan to add BFD multihop support to OpenBSD in near future?
: 2. Also, is there a plan to add a portable version of BFD to other platforms like FreeBSD and linux
