Hi,
I would like to get some feedback on the usage of the SID/Label Binding TLV.
Is there any implementation that uses SID/Label Binding TLV for
advertising the SID/Label binding to a FEC as specified in section 6 of
the draft-ietf-ospf-segment-routing-extensions-16 or section 2.4 of
draft-ietf-isis-segment-routing-extensions-12?
If not, do we see this as something we want to preserve in the IGP SR
drafts?
ISIS uses The SID/Label Binding TLV to advertise
prefixes to SID/Label mappings, which is known to be supported by
several implementations and that piece needs to be preserved.
thanks,
Peter

Acee,
my question is whether we need the whole section 6 and the SID/Label
Binding Sub-TLV that it specifies. In OSPF Binding SID is not used for
SRMS advertisement like in ISIS.
thanks,
Peter

Subject: OSPFv2 Segment Routing Extensions ERO Extensions (would also
effect OSPFv3 and IS-IS)
Hi OSPF, ISIS, and SPRING WGs,
As part of the Alia’s AD review, she uncovered the fact that the ERO
extensions in 6.1 and 6.2 are specified as far as encoding but are
not specified as far as usage in any IGP or SPRING document. As
document shepherd, my proposal is that they simply be removed since
they were incorporated as part of a draft merge and it appears that
no one has implemented them (other than parsing). We could also
deprecate types (4-8) in the OSPFv2 Extended Prefix LSA Sub-TLV
registry to delay usage of these code points for some time (or
indefinitely ;^).
Thanks,
Acee
