You sort of hit the wrong list, but if someone has good ideas how to solve
this for IOS, I'm all ears :-)

(Specifically what I'm looking for is something that hooks into IP SLA or
Ethernet OAM/CFM and takes a link out of IGP routing if packet loss crosses
a certain threshold - we recently had a carrier break their metro network
in interesting ways, leading to 50% packet loss, which was enough to
effectively take the site offline, but IGP stubbornly clung to "I have
seen a keepalive!")
