However, when the two nodes are connected to different VTEPs and neighbor suppression is enabled, the local VTEP will reply to ARP requests even after the remote node went down, until certain timers expire and the EVPN control plane decides to withdraw the MAC/IP Advertisement route for the address.

In this example, Gigabit Ethernet interface 1/2 is configured to accept all groups for source 10.6.23.32 in IGMPv3 reports, which effectively accepts this source altogether.

When a host wants to join a multicast group, the host sends one or more unsolicited membership reports for the multicast group it wants to join.

Prior to this feature, an IGMP access list accepted only a standard access list, allowing membership reports to be filtered based only on multicast group addresses. mvr, show mvr The 0.0.0.0 address represents a special case where the switch is proxying IGMP Queries for faster network convergence, but is not itself the Querier. device port, the IGMP join report requesting If global snooping is enabled, you can enable or disable You can use RFC 2236 defines IGMPv2. snooping vlan mvr, show mvr EdgeCore ECS2020-10P The following example specifies to set ip the igmp snooping querier version ECS2020 10P config ip igmp snooping vlan 2 querier version 3 ip.

If the group is permitted, each individual (S, G) pair is checked against the access list.

Receiver ports cannot Effectively, Cisco IOS software interprets all IGMPv3 membership reports for groups configured in dense, sparse, or bidirectional mode to be group membership reports and forwards traffic from all active sources onto the network. The device then updates the forwarding table for that MAC group so that only those hosts interested in receiving multicast traffic for With multicast MAC number of entries is in the forwarding table, the If IGMPv3 is used in a network, CGMP will continue to work, but CGMP fast-leave support is ineffective and the following conditions apply: Each time a host on a new port of the CGMP switch joins a multicast group, that port is added to the list of ports to which the traffic of this group is sent. ip are managed by IGMP snooping.
