There is a multi-ring topology, combined with 8 Hubs and 2 switches, i want to ask two questions
1. If H3 is damaged,but the fiber is still ok, will H2 damage too in the future? i have thinking to explain the reason, but i don't know it is right or wrong.
Reason: because H3 is damaged,so H2 will keep sending messages,m1, to H3 ,but H2 needs to send lots of other messages to H3 in the future,so this situation will cause too many messages need to be sent by H2, and it will let H2 be crashed, is this thinking right?
2. The hubs are JetNet 4006f ,and 4006f provide two redundancy technologies, rapid dual-homing and rapid super ring,and my friend tells me that i have to disable the rapid dual-homing ,just like the picture below,my friend and i don't know why,does anyone know the reason?i have a thinking too,but i don't it is right or wrong.
Reason:rapid dual-homing and rapid super ring are both redundancy technology,so i have to choose one of them,that is,if i choose the rapid super ring as the version,i can't enable the rapid dual homing.
