ip igmp snooping for to

I have read about this subnet range, it`s not possible to disable the snooping feature on a switch. So routing protocols (like OSPF or EIGRP) are always forwarded to other ports regardless the snooping feature. Is that true? Someone with more informations on that.

In general, addresses from to are reserved and used by various protocols (standard or proprietary, such as Hot Standby Router Protocol (HSRP)). Cisco recommends that you not use these for GDA in a multicast network. CGMP and IGMP snooping do not work with this reserved address range.
