I have a 3845 connecting to a 2811 through GRE tunnel. The GRE tunnel from the 3845 will pass through a ASA5520 to encrypt the GRE tunnel into an IPSec tunnel terminated on the 2811.
Occassionally, there is a drop to the tunnel interface independent of load of the tunnel. It is not a lot of drop however there is constantly 3-5 packet drops per minute.
I have checked the Loopback10 and the Ethernet interface and there is no packet drop from any interface. Traffic seems to be behaving properly however interfaces showing drops and not sure what is being dropped.
Is there anyway to find out what causing the drop?
I have enabled keepalive on the tunnel interface and it does not help. Actually, the log did not show there is any interface shutdown or lost of routing neighbour relationship. The physical interface does not show any drop either.
