Hierarchy Level


Set optimized inter-subnet 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.

pim-evpn-gateway external-irb name

Configure an IRB interface to act as a PIM EVPN gateway (PEG) on a device where you have enabled OISM. The devices uses the PEG interface to route multicast traffic to and from an external PIM domain.

supplemental-bridge-domain-irb irb-interface-name
