Regarding the strange ICMP packets(source and destination IP is NE itself, TTL is 2), actually this is a link detection mechanism. If the interface is up and received the packets, then NE will start the link detection automatically, it sends the ICMP packets(source and destination IP is NE itself, TTL is 2), the remote side receives this packet and will send it back to NE since the destination IP is the sender.After NE receives the ICMP packet, it will compare the packet, if the data has been modified or it is time-out, NE will consider the link is unstable or problematic.you can configure the below command to turn off the ICMP detection.
