Information About L2Multicast Route Update Optimization
Beginning with Cisco NX-OS Release 8.2(9) Multicast Route Update Optimization feature is introduced to avoid packet loss in the multicast group.
Before release 8.2(9), when two or more host connects to a multicast group, if one of the hosts disconnects from the multicast group, there is packet loss for the existing host in the same multicast group if multicast source and receiver are in the same vlan. This packet loss is on l2 multicast on M3 and F4 Series modules.
Note |
By default, this configuration is disabled. You must configure this feature using admin VDC or default VDC role to enable on multicast group. |
