using external zebra/openbgpd

How to setup an external zebra/openbgpd to do complex bgp including prioritization of providers etc ? Can we then make MT learn this ?? Since MT does not support the complex bgp features.
Any body done this ?

What we want to achieve is to prioritize traffic as well as set priority incoming routes so traffic comes via our set providers. Since we do full bgp.

Thoughts onhow to do are also welcome. I believe this will help many as well as make MT mainstay since all the other stuff is gr8.

later in 2.9 we will have more advanced BGP, you’ll have to wait for the final release

Any estimated time on 2.9 ?
As well as what features are supported. I dont want to be one of the early adopters and suffer any concequences, which is why i wanted to know how we can have a second box handle bgp and handout the routes to the main router.
