Hi Guys!
Very strange thing happening as I see. This bug is in state closed (!!!) So that simply meant that all unnecessary non-RPF traffic on my routers will remain, and I will have high load due to what? What about another IGMP - mroute related question? When router assumes that he must forward traffic to all(!!!) multicast enabled interfaces! That meant adding 5 Mbit/s as the source and having 10 interfaces you will have 5*10=50 Mbit//s (!!!!!!!) unnecessarry load!
CSCdr74908 + ip mroute bug which is not yet even answered by cisco+ 5 Mbits more traffic, which can be generated by trading software, and I will have 70% load!!!
