When configuring multicast for wireless on a network using EIGRP and BGP within a single domain from a single source, the appropriate type of multicast routing protocol to be implemented would be Protocol Independent Multicast Sparse Mode (PIM-SM).
PIM-SM is the most commonly used multicast routing protocol in enterprise networks, and it is designed to support sparse multicast groups, where only a small subset of the network devices are interested in receiving the multicast traffic.
In PIM-SM, multicast routers exchange join and prune messages to dynamically build multicast distribution trees from the source to the receivers. The source sends multicast traffic to the root of the distribution tree, and the routers forward the traffic down the tree only to the interested receivers. This helps to conserve network bandwidth and reduce unnecessary multicast traffic.
Other multicast routing protocols such as Protocol Independent Multicast Dense Mode (PIM-DM), Source Specific Multicast (SSM), and Multicast Source Discovery Protocol (MSDP) may also be used, but they have different design goals and may not be suitable for all network topologies and multicast applications.
PIM-DM is a flood-and-prune multicast routing protocol that floods multicast traffic throughout the network, which may not be suitable for large networks with many multicast groups and limited bandwidth.
SSM is a subset of PIM-SM that supports one-to-many multicast communication from a specific source to a specific group of receivers. SSM requires that the receivers know the IP address of the source and the multicast group in advance, which may not be feasible in some situations.
MSDP is used to connect multiple PIM-SM domains, but it is not necessary in a single domain network.
