Configuration Roadmap
The configuration roadmap is as follows:
1.
Configure EFM for links between CE1 and PE3 and between CE2 and PE4 to monitor link
connectivity.
2.
Configure EFM for the link between PE3 and PE4 to monitor link connectivity.
3.
Configure association between EFM and interfaces on CE2 so that if EFM detects a link
fault between CE1 and PE3, traffic can be switched to the backup link and return traffic is
not forwarded to PE4.
4.
Configure association between CFM and EFM on PE3 and PE4 so that CFM and EFM can
notify each other of faults.
Data Preparation
To complete the configuration, you need the following data:
l
MD names, MA names, MEP IDs, and REMP IDs
l
Names of interfaces associated with EFM
