I have two mx204s connected via 10G interfaces over a third party transport circuit. The circuit service is set for 5.5Gbps.
I have been trobleshooting a packet loss problem that is interferring wth 1Gbps bandwidh testing mostly in the downstream direction.
The circuit provider sasys they do not seeing any dropped traffic on their network for our circuit.
I just configured MPLS LSP performance monitoring and packet loss is being reported the the LSP that is transporting the traffic for the Internet speedtesting.
Model: mx204
Junos: 23.4R2-S3.9
How do I go about troubleshooting the lost traffic assuming the circuit transport is clean?
Pinging across the link shows no packet loss.
