Hi, > For example, group-address "233.252.0.23" has two source-addresses, which are 192.0.2.1 and 192.0.3.1. The 192.0.2.1 is include mode, and the 192.0.3.1 is in exclude mode. INCLUDE and EXCLUDE modes does not coexist in a single multicast address. So above explanation seems wrong. In your example, if you register 192.0.2.1 with INCLUDE, the application using the group-address 233.252.0.23 only receives content sent from 192.0.2.1(so that content sent from 192.0.3.1 is not received). If you register 192.0.3.1 with EXLUDE, the application using the group-address 233.252.0.23 receives content sent from all node except 192.0.3.1 (so that content sent from 192.0.2.1 is received).
