Both up MEP, down MEP and MIP are supported. If an up MEP is configured under an EFP within a bridge
domain, CFM messages would be routed into the bridge, and the rest members of the same bridge domain
would be able to receive messages from this MEP. If a down MEP is configured, the messages will not goes
into the bridge domain.

Designing CFM Domains
To have an operator, service provider, or customer domain is optional. A network may have a single
domain or multiple domains. The steps listed here show the sequence when all three types of domains
will be assigned.
Note
Before You Begin
•
Knowledge and understanding of the network topology.
•
Understanding of organizational entities involved in managing the network; for example, operators,
service providers, network operations centers (NOCs), and customer service centers.
•
Understanding of the type and scale of services to be offered.
•
Agreement by all organizational entities on the responsibilities, roles, and restrictions for each
organizational entity.
•
Determination of the number of maintenance domains in the network.
•
Determination of the nesting and disjoint maintenance domains.
•
Assignment of maintenance levels and names to domains based on agreement between the service
provider and operator or operators.
•
Determination of whether the domain should be inward or outward.
SUMMARY STEPS
1.
Determine operator level MIPs.
2.
Determine operator level MEPs.
3.
Determine service provider MIPs.
4.
Determine service provider MEPs.
5.
Determine customer MIPs.
6.
Determine customer MEPs.
