The RP is connected to the receiver nodes of the multicast session and the source nodes send the data packets to the RP based on the underlying unicast routing protocol.
AMRoute make use of the underlying unicast routing protocol to detect network dynamics while it takes care of the frequent tree reconfigurations.
ODMRP can also operate independently as an efficient unicast routing protocol.
CAMP heavily needs the support of the underlying unicast routing protocol to provide route updates .
Supporting QoS for multicast routing protocols is a challenging task compared to unicast routing protocols
. In unicast QoS protocols, the resource reservation is done between a source and a destination, while multicast QoS routing protocols should provide suitable QoS paths to all destinations of the multicast group .
There are two broad classifications of unicast routing protocols
: minimum-weight based routing and stability-based routing.
Similar to unicast routing protocols
, multicast routing protocols could be classified as either topological-based routing or geographical-based routing.
