Re: [Isis-wg] WG Adoption poll for draft-hegde-isis-advertising-te-protocols

[<[e-mail]>]

Hi Authors,

One question, why do you think it is really needed to introduce the SR flag ? Couldn't it be deduced from the presence of an Adj-SID and the SR router cap ?
The SR flag unset while the router supports SR looks strange to me. Why do you want to prevent "SR forwarding" on a link if the node supports SR ?

" With this information, a centralized
   application can decide to use a different path for that traffic by
   using a different label stack."
In such a case, the usage of a Node-SID may be complex, as the Node-SID may cross a link with the SR flag unset. This will force the controller to use Adj-SIDs only. 
If the controller uses only Adj-SIDs, then an implementation can allow the user to prevent the advertisement of Adj-SIDs on a particular link.

Could you clarify the use case here ?


Thanks,
