A host on R4's 172.16.20./24 subnet requests to join the 239.123.123.123 group. R4 sends a PIMv2 join message up to the RP (R1). Subsequent join messages are sent every 30 seconds, until R4 determines it no longer has any interested hosts and sends a prune request (packet #45). PIMv1 RP-Reachable messages for the group are also visible from R1.

Vi har som altid åbent mellem jul og nytår ☃ RFC3376 for IGMPv3 details support for source filtering, that is, the ability for a system to report interest in receiving packets ‘only’ from specific source addresses, as required to support Source-Specific Multicast [SSM], or from ‘all but’ specific source addresses, sent to a particular multicast address.

The aggregation network can insert up to two AP identifying VLAN tags, and the AP can insert a .1q tag (typically for identifying the SSID). The number of AP identifying tags sent on the internal epipe depends on the encapsulation on the access SAP.

The Internet Group Management Protocol (IGMP) is used by hosts to notify adjacent routers of established multicast (one-to-any) group memberships. In other words, IGMP enables a computer that provides content (video feeds), for example, to provide such content to a distributed group of users using one set of the multicast address ranges (in the 224.0.0.0 to 239.255.255.255 class D multicast ...
