kbfd is BFD(Bidirectional Forwarding Detection) implementation in Linux Kernel Module. It is available patch for zebra-0.95a. (quagga's patch also avaliable soon.) This could be control kbfd and utilize for ospfd/ospf6d/bgpd to use bfd fast failure detection. - base specification draft-ietf-bfd-base-05.txt draft-ietf-bfd-v4v6-1hop-05.txt draft-ietf-bfd-generic-02.txt (future plan) draft-ietf-bfd-multihop-04.txt draft-ietf-bfd-mib-03.txt - Requirement linux kernel version linux-2.6.16 source tree at least.
