Enabling And Configuring Gmrp; Managing Igmp Snooping - Siemens RUGGEDCOM ROX II User Manual

Chapter 5
Setup and Configuration
• Source S1 transmits multicast traffic to Port D2 which is forwarded via Port D1, which has previously become a
member of Multicast Group 1.
• Switch B forwards the Group 1 multicast via Port B4 towards Switch E.
• Switch E forwards the Group 1 multicast via Port E2, which has been statically configured for membership in
Multicast Group 1.
• Host H1, connected to Port E2, thus receives the Group 1 multicast.
• Source S2 transmits multicast traffic to Port A2, which is then forwarded via port A1, which has previously
become a member of Multicast Group 2.
• Switch B forwards the Group 2 multicast via Port B2 towards Switch C.
• Switch C forwards the Group 2 multicast via Port C2, which has previously become a member of Group 2.
• Ultimately, Host H2, connected to Port C2, receives the Group 2 multicast.
