CFM Support for EVPN
Ethernet Connectivity Fault Management (CFM) is a service-level OAM protocol that provides tools for
monitoring and troubleshooting end-to-end Ethernet services per VLAN. This includes proactive connectivity
monitoring, fault verification, and fault isolation. CFM can be deployed in an EVPN network. You can monitor
the connections between the nodes using CFM in an EVPN network.
Restrictions
CFM for EVPN is supported with the following restrictions:
• In an active-active multi-homing scenario, when monitoring the connectivity between a multi-homed
CE device and the PE devices to which it is connected, CFM can only be used across each individual
link between a CE and a PE. Attempts to use CFM on the bundle between CE and PE devices cause
sequence number errors and statistical inaccuracies.
• There is a possibility of artefacts in loopback and linktrace results. Either a loopback or linktrace may
report multiple results for the same instance, or consecutive instances of a loopback and linktrace between
the same two endpoints may produce different results.
For more information about Ethernet Connectivity Fault Management (CFM), refer to the Configuring Ethernet
OAM chapter in the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component
Configuration Guide.
EVPN Multiple Services per Ethernet Segment
EVPN Multiple Services per Ethernet Segment feature allows you to configure multiple services over single
Ethernet Segment (ES). Instead of configuring multiple services over multiple ES, you can configure multiple
services over a single ES.
