Hi Ketan, Thanks for your response..
The draft says: <snip> This document defines the B-bit in the LLS Type 1 Extended Options and Flags field. This bit is defined for the LLS block included in Hello and Database Description (DD) packets and *indicates that BFD is enabled on the link* and that the router requests strict-mode for BFD. </smip> You don't enable multi-hop BFD on a link, instead you enable it b/w two (multi-hop) routers, right? How about replacing it with: indicates that (1) single-hop BFD [RFC5881] is enabled on the link in case of point-to-point (numbered) and LAN interfaces, and (2) multi-hop BFD [RFC5883] is enabled between the neighbors in case of virtual links and point-to-point unnumbered interfaces. Also, add a note at the beginning of the draft that BFD refers to both single-hop and multi-hop BFD when not explicitly specified..
