Re: [PWE3] draft-ietf-pwe3-iccp interaction with draft-pw-redundancy-bit

Hi Daniel,

The ICCP draft does assume the use of the pw-redundancy-bit draft. Section
9.1.3 describes two modes of operation (depending on configuration):

- When an external AC redundancy mechanism is in use, and is being
synchronized among the PEs via ICCP. In this mode, PW state is not
synchronized via ICCP and the Independent Mode of operation is used for PW
state signaling. This guarantees that the AC and PW states are always in
sync for a given PE (to avoid deadlock).

- When an external AC redundancy mechanism is not in use, then PW state is
synchronized via ICCP. In this mode, either the Independent mode or the
Master/Slave mode could be used for PW state signaling.

We will add clarifications to that effect in a future revision.

Regards,
Samer
