We currently have a 3662 with a NM4E connected to the trusted interface of a NS10 VPN device. We are experiencing dropped packets while traversing via the tunnel. After starting some pings and putting a sniffer bet the 3662 and NS10 we noticed that a Looped: Receipt Reply = 0 frame from the 3662 appears at the same time as the packet loss. Can any tell me what "Looped: Receipt Reply = 0" means?
I tried looking up under CCO with no success
