Hi community,   We have a customer with hundreds of sites and we constantly get tickets due to one of their helpdesk techs seeing high loss rates out 1.1.1.1. It's important to note that they have multiple paths for redundancy, essentially 2 routers and 2 switches that are connected to each other twice with RSTP blocking enabled. I have attached their topology.    I have two questions: #1 Why does 1.1.1.1 show 100% loss at so many of the sites so often #2 Why does the utility show WAN1 and WAN2 3 times?   This is my suspected reason for having WAN1 and WAN2 listed 3 times-  For each WAN, respectively (flipflop the 1s and 2s for the 3 WAN2 connections): SEC1 to SW1 to ISP1 SEC1 to SW2 to SEC2 to SW1 to ISP1 - twice: Two ports connect between each sw to sec,        I have NO idea why we constantly see the 100% loss rates for 1.1.1.1. It causes our customer's help desk to generate tickets that the WAN is down because they see the loss rates in the graph. It drives both our NOC and the customer's NOC crazy.              Topology:    Any ideas on causes, fixes, workarounds? ... View more
