A colleague and I are having a debate over the following scenario....
We want to use a unidirectional serial port on an uplink router to simultaneously transmit multicast packets to a unidirectional serial port on multiple downlink routers. Only one of the multiple downlink routers will have a back channel. Will the one downlink router, that has the back channel, convince the uplink router to route the multicast packets over the uplink serial port to all of the downlink serial ports, simultaneously? All of the downlink routers will have members of a multicast group on an ethernet port.
That will not work. All of your downlink routers will need a back-channel back to the uplink because the uplink will determine where to send the multicast traffic based on which of the routers have sent it IGMP membership reports (via the back-channel).
We are pleased to announce availability of Beta software for 16.6.3.
16.6.3 will be the second rebuild on the 16.6 release train targeted
towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are
looking for early feedback from customers befor...
