Continuity fault management: Monitoring on pseudowire services interfaces

Junos OS supports IEEE 802.1ag connectivity fault management (CFM) on pseudowire service interfaces. Pseudowire service interfaces support configuring of subscriber interfaces over MPLS pseudowire termination. Termination of subscriber interfaces over PW enables network operators to extend their MPLS domain from the Access/Aggregation network to the service edge and use uniform MPLS label provisioning for a larger portion of their network. To enable support for CFM on pseudowire service interfaces, configure maintenance intermediate points (MIPs) on the pseudowire service interfaces. The CFM MIP session is supported only on the pseudowire services interface and not on the pseudowire services tunnel interface.
