Hey Srihari,

So yes or now.

You can treat them as different routes or just advertise paths. AIGP is
path attribute so we do not need to actually turn it into different net.

But irrespective on how it is done currently the draft seems silent on this
and IMO it should provide such solution day one.

Still like it though :)  In fact I prefer it vs CAR/CT proposals and I do
not see them as complementary as they do solve the same problem. I like
simplicity.

Cheers,
R.
