Operational groups, also referred to as oper-groups, are supported in EVPN services. In addition to supporting SAP and SDP-binds, oper-groups can also be configured under the following objects:
EVPN-VXLAN instances (except on Epipe services)
EVPN-MPLS instances
Ethernet segments
These oper-groups can be monitored in LAGs or service objects. Oper-groups are particularly useful for the following applications:
Link Loss Forwarding (LLF) for EVPN VPWS services
core isolation blackhole avoidance
LAG standby signaling to CE on non-DF EVPN PEs (single-active)
