Consider a network containing three hosts H1, H2, and H3. The network consists of a multicast router R running IGMP version 1. The list of currently active groups and the associated delay timers is as follows: Note: d) t1-7, t2 = 5, t3 = 4, t4-2,6-8, t6-6, t7-9. 4 Describe the sequence of responses that will occur in response to router R's query message (6 marks) H1 Group A (timer tl) Group B (timer t2) H2Group A (timer t3) Group B (timer t4) Group C (timer t5) H3Group A (timer t6) Group C (timer 17)
