Wouldn't you be better served just walking the netToMedia tables for your
devices? Parsing configs sucks. Even caching the contents of a simple
snmpwalk would save you some pain. Shovel 'em into a db and call it a day.

Well, True. But the idea is to have a full mesh of 'n' sensors each
doing 'tests' to the remaining n-1 sensors. Finding asymmetric routes
should be trivial as I plan to feed it my router configs from rancid,
for detecting interfaces that belong to the same router. ( Of course,
this can't be extended to the Internet in genral. )
From all the replies I have received, I don't think anything open
source fits the bill.
Going to the mines to write my own. Good bye cruel world...

2. actively detect routing changes / failover to redundant paths
using traceroutes
i.e. alert if SFO->CHG->NYC changes to SFO->LXE->HOU->NYC
( link state protocols suck as far as testing backup paths go)
Two words: "Asymmetric routes". Just be aware of the implications.
