Sam,
You can get the received routes via SNMP. I've done this manually on
occasion for the purposes of doing what-if analysis of potential
traffic plans - take a dump of all available external routes via SNMP,
apply to that the proposed policy with regard to selecting the best
route,
We used such system in Russia for many years, with a few exceptions:
-- did not used SNMP (because it is a sux!), used 'ssh/rsh router show ...'
commands instead;
- not top 10 traffic flows, but top 10 traffic flows + top 10 unusual
traffic flows.
Worked effectively.
To bring this back on
