One of our guys just cleared out the CEF table on the effected interface - now pings go through just fine ... As noted earlier, mere changes in packet options were enough to cause different behavior [I'm trying to find a Bug-ID associated with this ....] - Tom On Fri, 6 Oct 2000, Jeff Bartig wrote:

I'm currently looking into a weird problem at an ATM peering point on the West Coast, when I ping from my peer router to any of my peers I get some but not total packet loss, when I ping from one router back or use the loopback interface as source things are fine. Whereas, with all my other ATM peering point routers, for example at MAE-EAST I can ping my peers cleanly from the same router. This isn't (to my knowledge) affecting traffic just wondering why this strange phenomenon should occur only in the one place.
Have you verified the return path of the packets from your peers? Are they getting to you via that peering connection or taking a different path back to you?
