[nsp] how to force specific subnet out specific interface

[Stephen J. Wilcox]

Well, you can do policy routing so build a route map to match the ips and set 
next hop to isp2 then apply the policy to the other interfaces on the router (to 
catch packets as they come in)

But I'm not sure why you need to do this, is isp1 filtering you? you should be 
able to send packets sourced from your new subnet out via isp1 and receive the 
retujrn packets back via isp2 without issue.. if they are filtering perhaps you 
can persuade them to modify their filters even if they dont wish to accept your 
bgp prefix.
