Designing CFM Domains
Command or Action
Step 6 Determine customer MEPs.

Examples

The figure below shows an example of a network with a service provider and two operators, A and B. Three
domains are to be established to map to each operator and the service provider. In this example, for simplicity
we assume that the network uses Ethernet transport end to end. CFM, however, can be used with other
transports.
What to Do Next
After you have defined the Ethernet CFM domains, configure Ethernet CFM functionality by first provisioning
the network and then provisioning service.

Purpose
• Ensure the MIPs are at a maintenance level that is at least one higher than the highest
level service provider domain.
Customer MEPs are on customer equipment. Assign an outward facing MEP within an
outward domain at the appropriate customer level at the handoff between the service provider
and the customer.
