[PWE3] clarification on draft-muley-dutta-pwe3-redundancy-bit-02.txt

hi,

I am seeking some clarification on this draft.

1) in the beginning of section 5, the draft states that the preferential
forwarding bit is set to indicate Standby state, but later in draft in
section 5.3.1.e and 5.3.2.a.ii, the usage seem to have been reversed;
i.e. the latter paragraphs seem to suggest that when the preferential
bit is set, the PW is in Active state. Is there a contradiction here or
am I reading it wrong?

2) in section 5.3, The first sentence of the first paragraph states
"There are PW redundancy applications which require that PE/T-PE nodes
coordinate the switchover to a PW/MS-PW path such that both endpoints
will be forwarding over the same path at any given time."

Isn't that an implicit requirement for all PW redundancy applications
based on definition given in section 4. regarding what Active and
Standby state means? If there are PW redundancy applications where
forwarding at both endpoints can be on different paths, what would those
scenarios be?

thanks,
keng
