I have some comments on the proposed mechanism (I have no opinion on utility or likely implementation): 1. WRT SUMMARY_FRR_BYPASS_ACTIVE object RSVP object space is a pretty scarce resource and it seems we have a number of existing objects that could be reused to support transport of the required information. Some candidates include: the Association object with a new association type; or perhaps the PRIMARY_PATH_ROUTE Object with a new C-type. 2. SUMMARY_FRR_BYPASS_ASSIGNMENT subobjects While RFC4090 makes use of RRO carried information, it does so without changing the RRO format. (At the time, I recall some used this as justification for RRO usage vs introducing new formats.) The new SOs introduce new information and don't seem to be particularly linked to normal RRO operation -- and more significantly really defining new transit-node to transit-node signaling semantics: The PLR notifies the MP of the bypass tunnel assignment via adding a SUMMARY_FRR_BYPASS_ASSIGNMENT subobject to the RSVP Path message RECORD_ROUTE object ... The MP acknowledges the PLR's assignment by signalling a SUMMARY_FRR_BYPASS_ASSIGNMENT subobject within the RSVP Resv messsage RECORD_ROUTE object. IMO this usage of RRO is really wrong (and is easily broken by application of RRO policies). I think extending an existing object class is a better approach. Extending one of the existing FRR objects would probably be cleanest, but think the authors should consider and propose their preference.
