Configuring Multi-UNI CFM MEPs in the Same VPN

Effective with Cisco IOS-XE Release 3.14S, services can be configured, such that two or more bridge domains
(BDs) are used to achieve UNI isolation and backhauling towards provider edge (PE) device. Local MEPs
(with up direction) should be configured on the UNIs (with the associated BDs) to monitor the service backhaul
connection. To achieve this, use the alias command to configure a Connectivity Fault Management (CFM)
Maintenance Association (MA). For example, MA2 can be an alias to another MA, MA1. As a result, MA1
behaves as though it is configured as MA2 on a different BD associated with it. MA1 and MA2 function as
if they are part of the same service, thus associating the same CFM MA to two different BDs and achieving
UNI isolation.
The following figure shows the configuring Mutli-NNI CFM in the same VPN.

Purpose
Enables cross-checking between the list of configured
remote MEPs of a domain and MEPs learned through
CCMs.
