Multicasting in a network improves the efficiency to deliver an IP packet to multiple clients at the same time. Small to medium sized organizations implement this technology to enhance their network capability, which is otherwise not possible just with normal routing. However, to use this technology, it requires proper network design with tidy resource implementation.Network administrators prefer automatic deployment of multicast technology because it reduces the potential risk of prolonged down time during network troubleshooting. On the other hand, choosing an auto deployment technology could cause malfunctioning in the network. To avoid such malfunctioning, we used two technologies: Auto-RP (Auto- Rendezvous Point) [1] and Bootstrap [2] in our network. A problem that occurs here is that if different domains with similar or different technologies want to share their resources with each other, then regular multicasting cannot connect them for successful communication. Also, if an administrator wishes to provide short and redundant paths within a domain, then these two technologies do not possess the ability to do so.The thesis presents issues in intra-domain and inter-domain multicast networks; it also focuses on Auto-RP (Auto Rendezvous Point) and BSR (Bootstrap Router) which are technologies related to multicasting. This project highlights the importance of multicasting security and will brief the problems associated with these two technologies. It will offer a better solution with a properly implemented design guide. The study uses MSDP (Multicast Source Discovery Protocol) [3] which connects two domains with multicasting capabilities for exchanging the source and providing redundancy in intra- domain. The work implements MBGP (Multicast Border Gateway Protocol) [4] to avoid a situation in which there is no multicast support on one of the service provider(s) end.
