LPTS policing traffic, so i'd expect to see only some packets loss if the issue would be with LPTS, not all of them.

  • Does only ping traffic have problem?
  • Do you have this ping issue from both ASR9k pinging each other?
  • Can you ping your own IP address on every router?
  • Verify if you have any drops during the ping test matching the icmp packets:
  • Apply a hardware ACL with your source and destination IP address in order to verify if we see our icmp packets on the LCs for ingress and egress directions.
