Version: 1 for IGMP v1. Type:

IGMP v2 IGMP v2 výhody oproti IGMP výhody oproti IGMP v1 v1

IGMP version 2 extends the functionality of IGMP while maintaining backward compatibility with IGMP v1.

IGMP v2 adds new message types, an IGMP v2 Host Membership Report and a Leave Group message. It also adds a variation on the Host Membership Query called the Group-Specific Host Membership Query.

The details of these new message types are discussed in the following sections.


Type:

0x110x11 ＝＝ Membership QueryMembership Query - General Query, used to learn which groups have members on an attached network. - Group-Specific Query, used to learn if a particular group has any members on an attached network.
