48.4.7 MSDP Configuration Examples
Example 1: MSDP basic function.
Multicast Configuration:
1. Suppose the multicast server is sending multicast datagram at 224.1.1.1;
2. The designated router – DR, which is connected to the multicast server, encapsulate the multicast
datagram in the Register packets and send them to the RP(RP1) in the local domain;
3. The RP unwraps the packets and sends them to all the domain members through the shared tree. The
members in the domain can be configured to be or not to be in the shared tree;
