Multicast 239.255.255/24 – UPnP Filtering
Please be aware that if protocols such as Microsoft Universal Play and Play (UPnP) are enabled, multicast
addresses in the 239.255.255/24 may be seen by SPB bridges depending if protocols such as UPnP is
enabled on a Microsoft host. If you wish to deny the 239.255.255/24 address space, either an IGMP access
list can be created at a VLAN level or an ACL can be created at a port level.
IGMP Access List – Assuming the local VLAN is using an IP subnet of 10.14.10.0/24.
VSP 9000 and ERS 8800:
ip prefix-list UPnP 239.255.255.0/24
interface vlan 10
ip igmp access-list "UPnP" 10.14.10.0/255.255.255.0 deny-both
exit
VSP 4000/7200/8000:
ip prefix-list UPnP 239.255.255.0/24
interface vlan 10
ip igmp access-list "UPnP" deny-both
exit
show ip igmp access
