How does Rip send it's updates? It multicasts them to reserved addresses. In IPv4 this is 224.0.0.9, but what is it in IPv6? FF02::9. So your access list is blocking multicast traffic sourced from R6 to the multicast address. Since the access list is configured on R5, R6 will still be sending them, R5 will just ignore them. So now R5 isn't going to get these routes at all, however R7 will. R7 will not advertise them to R5 however because it is on the same subnet it learned them on. If we disable split horizon on R7 then it can advertise them back to R5. Now R5 receives them from R7 and not from R6.

Int f0/1 speed 100 duplex full bandwidth 10000 Which speed will the interface use for QOS? Will you see that in a duplex mismatch?
