Hi All,

With regards to RFC2547 Bis Option B , MPeBGP VPNv4 Between ASBR, I have tried
using :

CE ------ PE -------- P --- asbr -------------asbr --- p -- PE --------ce

<------------as1---------------------------><------------------
AS2---------->

1. Next Hop Self on ASBR towards its MPiBGP neighbours
2. Redistribute Connected Subnets.

Well In some documentation ,I came across a config which says ASBR( as1)
configured with a Next Hop Self towards Other ASBR (AS2).
Esp Documentation -- Networkers 2007 - Slide 14 of BRKRST-2105 .
I would apreciate if someone could clarify.

Thanks
Shubha Brata
