On Vol2 Lab 9 there is a Multicast Task 5.1 with the requirements:
Windows media server located on VLAN 3 is streaming a multicast video feed into your network. You have received complaints from users in VLAN 6 that they are unable to receive these feeds.
• Configure the network to resolve this problem.
• For further testing purposes, ensure that R6 responds to ICMP echo requests sent to the multicast group 224.6.6.6 sourced from VLAN 3.
• Do not change PIM mode settings on any interface
As there is a frame-relay connection between the routers, RPF Failures will occur.
I was checking the SG and they've create an interface tunnel and put a static ip mroute pointing to the tunnel interface.
In the real world, it would work ok, but in the lab exam it is explicit deny to put any static route to fix a issue unless specified by the task. This task doesnt specifie that we can use static route, so I can consider the SG is wrong, right ?
I've done that task the other way, altering the metric to R2 prefer to reach vlan 3 via fa0/0 interface instead of Fram-relay interface.
