IP Multicast config-lite for Fabric Connect
With IP Multicast config-lite for Fabric Connect you can configure Layer 3 IP
Multicast routing over Fabric Connect using a Layer 2 edge node without associating
an IP address on the VLAN. When you configure an MVPN I-SID on a VLAN, a dynamic VRF
named l3vsn is
created, and ipvpn is configured.
Dynamic VRFs are not present in the running config
and are not saved.

Note
ipvpn enable is not configured on this VRF.You can convert a dynamic VRF to a static VRF by using typical VRF creation with the
VRF name. For more information, see Create a VRF Instance.
Configure ip spb-multicast enable
on a VLAN interface without an IP address to avoid depleting the IP address pool of
the network. IP Multicast config-lite for Fabric Connect requires no additional
licensing.

Note
If a VRF with the same I-SID already exists on the device, the VLAN is associated with the existing VRF when you enter mvpn-isid on the VLAN.![Note](images/note.png)
Note
Manually configuring Layer 3 VSNs is not available.
