When a CFM-enabled L2VPN is connected to an L3VPN, dual-ended frame loss measurement is enabled to collect detailed statistics and monitor link quality.
When a CFM-enabled L2VPN is connected to an L3VPN, dual-ended frame loss measurement can be performed periodically.
Frame loss measurement is deployed on end-to-end MEPs. In Y.1731, frame loss statistics are collected based on the transmit and receive counters carried in CCMs. Dual-ended frame loss measurement can be successfully performed only when the RMEP is in the Up state.
