the sectionUnderstand the Problem and Its Solutionscovers this topic. If you statically configure an mrouter port on all the switches, IGMP reports can be relayed in that VLAN to all switches. As a result, multicasting is possible. So, in the example, you must ...
Were the swtches showing any signs of CPU hit when you get the performance problems ? Have you enabled IGMP snooping on the switches to stop multicast traffic being flooded to all ports. Unless your switches are getting overloaded because of the multicast traffic i'm not sure how PIM Sparse ...
Am I missing any additional configuration on the core switch? Also, do I need to configure anything else on the other switches in the network besides IGMP Snooping? I would greatly appreciate any suggestions or assistance in resolving this issue. Best regards. I have this problem too...
This issue can occur in Cisco Catalyst 6500 switches, which are configured for egress multicast replication mode and can be triggered by removal and re-insertion of any line cards [OIR]. After OIR, the Fabric Port Of Exit [FPOE] can be misprogrammed, which can cause packets to be directed...

http://www.cisco.com/go/nfp/ Future Work A number of areas have not been explicitly discussed in this paper. These include MVPN and Label Switched Multicast, firewalls and address translation. We have deliberately not focused on SP or enterprise-specific issues in this paper, and preferred to...
32:1 ambiguity that arises when Layer 3 multicast addresses are mapped to Layer 2 MAC addresses means that there are several multicast group ranges besides the 224.0.0.0/24 that will map to the 0x0100.5E00.00xx MAC address range and hence will be also be flooded by most Layer 2 switches....
“logical”multicast treemade up of switches/routers and network links. The multicast tree may be a rooted tree, where a source is at the root and all possible receivers connect to the root via branches or shortest possible paths between the source and each of the receivers. This works well...
Cisco On Cisco switches, IGMP snooping is enabled by default. You do have to enable an IGMP snooping querier though: ip igmp snooping querier This will enable it for all vlans. You can verify that it is enabled: show ip igmp snooping querier Vlan IP Address IGMP Version Port --- 1 172...
However, [22] analyzed power measurements obtained from a variety of switches from well-known vendors such as Cisco, ProCurve, and Brocade. They identify various control knobs as a function of switch configurations and traffic flowing through the switch. Based on their analysis, they developed a ...
