Working Group,

As we discussed in Montreal at IETF-105, the last hang up on progressing the
authentication documents (thread copied below) was concerns on the IPR
against them.

The holder of the IPR believes their discloures are consistent with prior
IPR posted against the BFD suite of published RFCs.o

We are thus proceeding with the Working Group Last Call for these documents.
You are encouraged to provide technical feedback for the contents of the
documents, which addresses providing stronger authentication on the BFD
protocol.  

Please indicate whether you believe these documents should be advanced to
the IESG for publication as RFCs.

-- Jeff and Reshad
