OcNOS SP : Carrier Ethernet Guide : Carrier Ethernet Configuration : Ethernet CFM Configurations
Ethernet CFM Configurations
This chapter discusses Ethernet Operations, Administration and Management (OAM) configuration using the Connectivity Fault Management (CFM) protocol.
CFM detects, verifies, isolates and notifies connectivity failures on a Virtual Bridged LAN (B- VLAN) based on the protocol standard specified in IEEE 802.1ag 2007. It provides discovery and verification of paths through 802.1 bridges and LANs and is part of the OAM module. CFM is transparent to customer data being transported by a network and is capable of providing maximum fault management.

EVPN-ELINE CFM Sub-Interface on Multi-Homing
The Connectivity Fault Management (CFM) feature enhances the product offering for the Ethernet LINE (ELINE) services in multi- homing scenarios. To route the traffic between two routers, create two sub interfaces within the physical interface, assign each sub interface an IP address within each subnet and then route the data between two subnets.
CFM multi-homing allows customer edge (CE) device to connect more than one provider edge (PE) device. Multi-homing ensures redundant connectivity. The redundant PE device ensures that there is no traffic disruption when there is a network failure.
The following topology, configurations and validation section describe EVPN-ELINE CFM Sub-Interface on Multi Homing devices.
Topology
The following topology consists of customer edge routers CE1 and CE2 with IPv2 Provider Edge routers PE1 and PE2. These are interconnected through the core router P in the IPv4 MPLS provider networks.

VPWS-CFM and Y1731 over Sub-Interface
To route traffic between two routers create a sub interfaces within the physical interface and assign each sub interface an IP address within each subnet and then route the data between two subnets.The Connectivity Fault Management (CFM) feature enhances Ethernet LINE (ELINE) services. CFM encompasses Continuity Check (CC) and Ping that help with network fault detection and isolation
Virtual Private Wire Service (VPWS) on EVPN-MPLS communicates between two customer points and establishes an EVPN instance between a pair of PEs in a sub interface. It forwards traffic from one network to another network without any Media Access Control (MAC) lookup.
Topology
The following topology consists of customer edge routers, CE1 and CE2 with Provider Edge routers PE1, PE2. They are all connected through the core router P in the IPv4 MPLS provider network.
VPWS-CFM and Y1731 over Sub-Interface
