Hi Rob,
Thanks for reverting back the mail.
If there is a desire to control traffic flows on individual bundle interface,
information about each of the bundle members interface is required to be
flooded
using IGP extension. Segment routing framework is generic and flexible enough
to handle this.
IGP extension need to support it.
There exist an ISIS Draft to handle it which I got to know yesterday from Les
Ginsberg
Advertising L2 Bundle Member Link Attributes in IS-IS
draft-ginsberg-isis-l2bundles-00.txt
I feel it's better to have all related information in one draft rather than
having multiple drafts
To distribute related information.
One small use case would be monitoring availability of bundle interface
availability.
We can find reference to it in "Segment Routing Use Cases"
6.1. Monitoring a remote bundle
