Hi All,

I believe this topic is relevant and something for the WG to adopt and work on.

I have some concerns though on it's applicability and more specifically it's implications on existing deployments/use-cases. I've share the same on the thread started by Joel on this specific aspect [1]. Some discussion and clarity on this would help before adoption.

One other bit, for the example in Sec 2.3, perhaps some text is required to clarify that this applies only for segments signalled via IGPs and if the 9054 was a BSID or BGP-EPE SID then this approach would not work. May I suggest to add a section 2.4 to capture these aspects (it would be some what on the lines of Sec 3.4 but not related to the context table solution).

The document is well-written and detailed. It does a very good job of describing the node protection scenarios and options.

Thanks,
Ketan
