[j-nsp] icmp problems tracing through m20's

[David Brazewell]

Hi

has anyone ever experienced problems where icmp traces (using mtr) to 
destinations through an m20 show no packet loss at the last hop but 
varying amounts of packet loss on one of the juniper interfaces?

tracing to the juniper itself shows no packet loss.

It has been suggested that this may be down to default icmp throttling on 
the junipers. does anyone know anything about this?

Thanks

David
