Questo documento mette in evidenza la configurazione necessaria per abilitare una comunicazione multicast tra due Virtual Machine (VM) vmware in cluster con una architettura computing costituita da due vswitch (no distributed-switch) e due ESXi node differenti collegati ad un dominio di switching Nexus N9300-EX.

 

L’architettura di riferimento è la seguente:

 

igmp querier nexus

 

 

Esempio di configurazione:

 

Switch-Nexus:

 

vlan configuration 100

ip igmp snooping querier 192.168.1.1

ip igmp snooping querier 192.168.1.3

!

 

N9K-1# sh ip igmp snooping vlan 100
