    Limitations on Junos Fusion with Multicast

    Junos Fusion strives to optimize data replication on satellite devices when local replication is enabled; however some features are not supported with local replication. For the following features, Junos Fusion does not trigger egress replication optimization; only ingress replication occurs.

    • Multicast support on pure Layer 3 extended ports
    • Multicast Listener Discovery (MLD) snooping on an IPv6 network

    Egress multicast replication is incompatible with some of the features on Junos OS. The following features will not work when egress multicast replication is enabled. If you choose to either enable egress multicast replication, you will not be able to use the feature.

    • VLAN tag manipulations, such as VLAN tag translations, VLAN tag stacking, and VLAN per-port policies. Using egress multicast replication with this feature can cause dropped packets due to unexpected VLAN tags.
    • Multicast support for the extended ports on the edge side of Pseudowire connection in VPLS networks.
    • Multicast support for the extended ports on the edge side of EVPNs.
    • Multicast VPN deployments.
    • MPLS/BGP VPN deployments.
    • Features that perform egress actions on individual extended-ports, such as egress local-port mirroring.
