The following errata report has been submitted for RFC4090,
"Fast Reroute Extensions to RSVP-TE for LSP Tunnels".

You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=4090&eid=4203

--------------------------------------
Type: Technical
Reported by: Yakov Rekhter <[email-masked]>

Section: 6

Original Text
-------------
Whenever the PLR has a backup path available, the PLR MUST set
the "local protection available" flag.

Corrected Text
--------------
Whenever the PLR has a one-to-one backup LSP or bypass tunnel 
available, the PLR MUST set the "local protection available" flag.

Notes
-----
In the case of facility-based FRR the PLR must set the "local protection available" flag if it has the bypass tunnel available.

Instructions:

Hi Yakov,

Could you clarify your point for this errata?  In RFC 4090, in the
terminology it says:
" Backup Path: The LSP that is responsible for backing up one
                       protected LSP.  A backup path refers to either a
detour LSP
                       or a backup tunnel.

  Backup Tunnel: The LSP that is used to backup up one of the many
                 LSPs in many-to-one backup."

Thanks,
Alia

In the terminology it also says:

   "Bypass Tunnel: An LSP that is used to protect a set of LSPs
            passing over a common facility."

My point is that (unless the term "bypass tunnel" means the same
as "backup path" or "backup tunnel") in many-to-one backup
the "local protection available" flag for a given protected LSP 
MUST be set when the PLR has a *bypass* tunnel for that LSP.

Yakov,

> MUST be set when the PLR has a *bypass* tunnel for that LSP.

Ah - ok.  A backup path that uses a bypass tunnel is not just the bypass
tunnel
itself.  There's the state associated for the protected LSP that also needs
to be
created and installed.  In more concrete terms, this is installing an
out-segment with
the appropriate label for the protected LSP to be understood by the merge
point as
well as an outer label for the bypass LSP.

So, the text refers to a backup path instead of a bypass tunnel because
having the
bypass tunnel isn't quite sufficient.  Does that make sense to you?

Regards,
Alia

Alia,

Correct.

The current text is incorrect. This is because a PLR may signal a
backup path at the time of failure. Yet, one should not wait for
the failure to set the "local protection available" flag. The PLR
should set this flag as soon as it has a *bypass* tunnel.

Yakov.

Yakov,

> should set this flag as soon as it has a *bypass* tunnel.

The backup path is created by the PLR before the failure and thus, before
the
associated signaling.  Once the PLR has done the work to create a backup
path using
an existing bypass tunnel - which is internal work - then the PLR should set
the "local protection available" flag.

Perhaps we should step back and ask whether the quote from section 6:

talks about forwarding state or control plane state. Is there
any text in rfc4090 that answers this question ?

Yakov.
