Hi Jeffrey,

Zzh5> It’s “outside the scope” of RFC9012, not that TEAs are **prohibited**
> with other AFI/SAFI.

What I should say was prohibited without a new spec extending the use of
TEA to other AFI/SAFIs. To the best of my reading the subject draft does
not extend use of TEA to other AFI/SAFIs.

Zzh5> That draft is about signaling **policy** - a totally different use

Sorry but SR policy is exactly for steering traffic to the tunnel endpoint.
Yes the name "policy" is chosen very poorly as it does not reflect what
most of us understand by "policy" but it is what it is.

Thx,
R.
