About Ethernet CFM
As shown in Figure 63-2, domains cannot intersect or overlap because that would require management
by more than one entity, which is not allowed. Domains can touch or nest (if the outer domain has a
higher maintenance level than the nested domain). Nesting domains can be useful when a service
provider contracts with one or more operators to provide Ethernet service. Each operator has its own
maintenance domain and the service provider domain is a superset of the operator domains. Maintenance
levels of nesting domains should be communicated among the administrating organizations. CFM
exchanges messages and performs operations on a per-domain basis.
