Re: [Idr] I-D Action: draft-ietf-idr-bgp-model-04.txt

Hi Mahesh,

Thanks for the update.

I'd like to comment on the new changes at a high level:

1) rib extension

This paradigm is inconsistent with other protocol models like ospf and
isis, where the protocol specific routes are kept under the protocol
instance tree, not under the /rt:routing/rt:ribs. Based on RFC8349, the
/rt:routing/rt:ribs tree is used to model the routes per routing instance,
which is better mapped to the Route Manager (whose name varies depending on
the implementations).

2) module ietf-bgp is missing

Is it intentional to remove the main module ietf-bgp? The description says
that bgp model augments the ietf-routing, but there is no such an augment
statement in the draft. I assume that the augment statement is in the main
module ietf-bgp.

Thanks,
- Xufeng
