Multicast Global Configurations
The Multicast Global Configurations screen is only for globally enabling or disabling the multicast
routing protocols on the switch. Each VLAN or IP Interface uses these global values unless you

enable it on a specific VLAN or IP interface. (RIP is globally set up with the RIP Configuration
option.)
To configure globally the multicast protocols
1. In the left panel, click Layer 3 IP Networking.
2. In the top panel under IP Multicast Routing Protocols, click Multicast Global
Configurations.

RIP packets. This field toggles between Disabled, V1 Only, V2 Only, and V1
