OpenBGPd has a couple of cool things, notably irr-filter. However, it  
cannot choose best path based on IGP metric to reach the BGP next hop.  
When you have multiple border routers with multiple routers between  
them this is really annoying.
As OpenBGPd and OpenOSPFd are different daemons and the OS[1] has no  
concept of metric, it doesn't work so well.

Until it can do this, I'm sticking with Quagga for host based routers.
Useful for route servers at an IXP though (if your IXP has route- 
servers) - irr-filter is very useful here.

It also did this weird thing where I'd route 2002::/16 at an stf(6to4)  
interface and OpenBGPd would do a recursive lookup and install the  
route with a next-hop of my local interface, or something weird like  
that. Quagga did what I expected so I stuck with it.
