Configure IP Multicast config-lite for Fabric Connect

About this task

Use mvpn-isid to dynamically create a VRF on one of the reserved Layer 3 VSN VLANs. The dynamically created VRF, l3vsn-<I-SID number>, obtains the I-SID number from the mvpn-isid command.

Note

If you are using a DvR leaf instance, the VRF name is l3vsn-<l3isid>.

You can use the ip spb-multicast enable command on that VLAN without configuring an IP address.

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

You cannot have an IP address and mvpn-isid configured on the same VLAN at the same time.

1. Enter VLAN Interface Configuration mode:

   enable

   configure terminal

   interface vlan <1–4059>

2. Configure an MVPN I-SID on the VLAN:
   mvpn-isid <0-15999999>[0-511]
3. Optional: Configure a routed SPB querier source IP address:
   ip igmp routed-spb-querier-addr {A.B.C.D}
4. Enable SPB Multicast on the VLAN:
   ip spb-multicast enable

Example

Enable SPB Multicast for a VLAN:

Switch:1>enable
Switch:1#config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch:1(config)#interface vlan 10
Switch:1(config-if)#mvpn-isid 100
Switch:1(config-if)#ip igmp routed-spb-querier-addr 192.0.2.1
Switch:1(config-if)#ip spb-multicast enable

Switch:1#show ip igmp interface vrf l3vsn-100
