<div>Hello,</div>
<div> </div>
<div>Looks like some sort of table mismatch conditon, since all the log entries report ,"entry exists"...so the add entry request by software seems to have failed...</div>
<div> </div>
<div>"What led to this condition ??"... would need further debugging from your side...</div>
<div> </div>
<div>The mcast groups that have reported this problem i.e. effffffa (239.255.255.250), e00000fc(224.0.0.232), e00000fc (224.0.0.253) are locally scoped addresses. I dont think they are part of your IPTV streams. </div>
<div> </div>
<div>So a mismatch in these shouldnt have resulted in IPTV failure. Unless, there are lot of these entries and has led to the entire IPMC (IP multicast) table going into a mismatch condition. </div>
<div> </div>
<div>I am not sure what the multicast network setup is, but it would be a good idea to ensure locally scoped addresses are limited to LAN and if these are not in use are blocked via acl's....examining the number of entries and the IPMC table details (i.e if too many entries are tied to the same egress, or there are too many source and subscribers to the same group etc), might help you minimise the churning of entries and help you get to the root cause faster...</div>
<div> </div>
<div> </div>
<div>regards,</div>
