None.

This example shows how to display the multicast forwarding cache table. In this case, it shows there 
are two source multicast networks. The network at IP address 165.223.129.0 is in multicast group 
224.2.164.189

. 

It recognizes an upstream neighbor at 134.141.20.1 via the VLAN 20 interface, and 

two downstream VLANs. The other multicast network at IP address 134.141.30.0

 

is in multicast 

group 238.27.2.2

. 

It recognizes the same upstream neighbor via the same interface, and four 

downstream VLANs. The table shows that two VLANs have asked to be pruned from this multicast 
distribution route:
