Re: [Isis-wg] FW: New Version Notification for draft-ginsberg-isis-sbfd-discriminator-00.txt

Hi Jeff,

We have had very lengthy discussions on this. As Les said, we could discuss as part of BFD effort. In fact I am looking forward to such discussion :D

Cheers

However, the additional information that may be required to differentiate how - when multiple discriminators are advertised by a node - each discriminator should be used is out of scope for the IGP advertisement. This gets into the area of application information which has to be defined/standardized elsewhere and does not belong in the IGP advertisements. So the deliberate intent here as far as the IGP advertisement is to limit it to simply a list of assigned discriminators - nothing more.
