• ○

  Receivers are generally unknown by the sourcE.

• ○

  Receivers are generally known by each other, since any receiver may be a sourcE.

• ○

  It is well suited for applications in which the receivers provide feedback to each other and the sourcE.

• ○

  All devices are potentially capable of generating multicast datA.

• ○

  It is well suited for applications such as video on demand, where each source sends a separate data stream to each of the many different receivers.

  The bootstrap router gets and propagates RP information via multicast messages
  

• ○

  The bootstrap router gets and propagates RP information via unicast and multicast messages
  

• ○

  BSR relies on timers to discover that an RP-Candidate router is no longer available
  

• ○

  For BSR to work, every router in the multicast network should be configured as BSR candidate

  Hello and Join/Prune messages use All-PIM-Routers multicast address (FF02::D) as destination.

• ○

  Register messages use the RP's global unicast IPv6 address as destination.

• ○

  Hello and Join/prune messages use the outgoing interface's global unicast IPv6 address as source address.

• ○

  Register messages use the outgoing interface's global unicast IPv6 address as source address.

• ○

  This is another term for asymmetric routing
  

• ○

  This refers to having different routing policies or routing topologies for unicast and multicast networks
  

• ○

  This refers to the case when the base routing table imports routes from two different protocols
  

• ○

  This refers to the case when unicast and multicast routing tables contain the same route entries

• ○

  Multicast CAC allows a service provider to guarantee the availability of mandatory IPTV channels
  

• ○

  The aim of multicast CAC is to maintain the quality of existing IPTV channels by rejecting new channel joins when required
  

• ○

  Multicast CAC measures the current bandwidth utilization on the physical links and then decides whether to accept a new channel or not
  

• ○

  Multicast CAC policy can be applied to VPLS SAP and SDP with IGMP-snooping

  Traffic for the 33rd multicast flow is droppeD.

• ○

  Traffic for the 33rd multicast flow is transmitted on the I-PMSI.

• ○

  The source PE reassigns the S-PMSI with the smallest flow to the new multicast flow. Traffic for the smaller flow is transmitted on the I-PMSI.

• ○

  The source PE re-uses an S-PMSI that is currently in use for the 33rd flow. Traffic for both flows is sent on the same S-PMSI.
