I have a video camera (5-10 mb/s) l2 service thats reported loss over a large private microwave circuit. (Along with other services) with a mix of routers. The core is comprised of ccr1009s, and the edge routers are a mix of rb1100ah4 and 3011s. I thought I had a switching issue / layer1 on the camera end, but for a trial, I change the l2 service from VPLS to EOIP, and video loss reported from the NVR dropped to nothing for over a the last two weeks. (The EOIP circuit is over MPLS as well.) Previously, if I reset the loss counters, they would start to increment within a few hours. The routers themselves are not reporting packet loss.
OSPF/MPLS backhaul, all running 6.47.7 and 6.47.8. Only providing l2 extensions for customers. CPU utilization does not ever exceed 1-2% overall, and 5-10% on any one core, on any devices, and its a private backhaul network, so no fw filter rules, just mangle prioritization of ospf/ldp on output. There arent even any queue's running because its limited to one device.
Any suggestions on why I am finding things to work this way? It seems everything Ive read says vpls should be better, but eoip seems to have less loss?
