eBGP Multihop

[Graham Beneke]

I have been asked to investigate moving an entire network to multi-hop 
on all the eBGP sessions. Basically all upstreams, downstreams and peers 
will eBGP with a route reflector located in the core. This RR will be 
some kind of quagga or similar box. The dev guys want to be able to poke 
at the BGP feeds directly and do *magic* that standard router aren't 
capable of.

My gut feel is that this is a bad idea. Besides anything else it makes 
sane link state detection very challenging - especially where we have 
multiple sessions with a peer.

Is their any BCP or operational experience that agrees or disagrees with 
my gut. ;-)
