Hi Thibault,
thank you for your interest in the draft, much appreciated. Please don't be
discouraged that it lapsed, we can fix it easily. I think that authors had
similar to your idea when we've started thinking about BFD supporting VRRP.
And like you we haven't found any reference in existing documents, hence
this draft draft-nitish-vrrp-bfd. Would be much obliged if you review and
share your comments, suggestion regarding solutions proposed in the draft.

Regards,
Greg
