Hierarchy Level


Set optimized intersubnet multicast (OISM) options in a Layer 3 virtual routing and forwarding (VRF) routing instance on an EVPN fabric device.



Originate selective multicast Ethernet tag (SMET) routes on revenue VLANs (or bridge domains) upon receiving a local IGMP report. SMET routes are EVPN Type 6 routes. The revenue VLANs are the customer VLANs that serve the hosts on the access side.

By default, when an OISM device receives a local IGMP join request, it originates a Type 6 route on the OISM supplemental bridge domain (SBD). With this option, the device also sends Type 6 routes on the revenue VLANs.

This option is helpful for compatibility with other vendor devices that don't support OISM. Those devices can't create the right states for the revenue bridge domain VLANs upon receiving Type 6 routes on the SBD.
