[isp-bgp] BGP & Policy Routing

[Chris Davies <isp@...>]

I take defaults from two providers as the router I have cannot handle 
full routes.  I have inbound ASpadding working properly, but, would like 
to direct traffic a little differently for one of my /22 blocks to add a 
'Quality of Service' benefit.  I've tried everything with policy 
routing, but, no matter what, showing the policy reports that it is in 
use, but, no packets are counted and routing is not adjusted.

How do I take all traffic originating from my one /22 block and default 
it out the secondary provider?  I know that route-maps actually are 
filtering the inbound and outbound announcements, but, I need to check 
what the source IP is and decide to throw it out my secondary connection.

I've checked policy maps, route maps, I thought perhaps with communities 
I could reset the next-hop, but, nothing appears to make a dent in it 
and everything defaults out the primary provider.  Of course, in the 
event of a failure of the secondary provider, I would like the 
connection to failover to the first.

Any hints or pointers in the right direction would be appreciated.  Thanks.
