Hi Alex,

in earlier revisions of the ietf-routing module (up to draft-ietf-netmod-routing-cfg-17), we had a configuration item ("recipient-ribs") that allowed for assigning RIBs to routing protocol instances. The reason for removing it is summarized in my presentation from IETF 92, slides 10 and 11:

https://www.ietf.org/proceedings/92/slides/slides-92-netmod-9.pdf

(and yes, I wasn't a big fan of this change).

Maybe Acee can give additional background.
