Hi,
I'm trying to use the Cisco Auto tunnel Traffic Engineering feature to improve convergence times; with FRR, these still appear to be of the order of 1 second not the sub second fail-over I was expecting to see. With a standard Windows ping, one or two polls are always lost and CCTV traffic picture sync is lost on each occasion. The NHOP/NNHOP backup tunnels appear to work correctly; fails over to NNHOP.
The network is a mix of ME3600 (PE) and C6509 (P) providing L3VPN services.
