(WG Chair hat Off, this is merely a note from a slightly confused WG
participant.)
I have been reading the various repair drafts, and the various networks
programming and service programming draft, and I am trying to figure out
one aspect of the combination.
How does a node that is doing some form of bypass (suppose, for
simplicity, it is Node N2 deciding to bypass the next SID for a failed
node N3) know that it is safe to do so?
If the path was just for TE, then it is "safe" if the new path meets the
TE criteria. or maybe it is safe if it is even close, as long as it is
not used for too long.
But what if the node were a Firewall, included to meet legal requirements?
Or was some other necessary programmatic transform (wince we are
deliberately vague about what nodes can do when asked suitably.)
Is there some "can be bypassed" indication in the routing advertisements
that I missed?
Thank you,
Yours,
Joel
