Symptom
IGMP querier does not work for the VLAN where it is configured. Issue happens when the querier configuration with the same "IP ADDRESS" is removed from one ToR switch and configured on another. The second switch assumes the querier is the same and is still working, so a new election does not happen.
Conditions
- Nexus 9k running below 7.0(3)I5(1).
- IGMP querier is configured:
vlan configuration 10
ip igmp snooping querier 192.0.2.1
- Querier is not seen on the IGMP state:
IGMP Snooping information for vlan 10
IGMP snooping disabled
Lookup mode: IP
Optimised Multicast Flood (OMF) disabled
IGMP querier none
Switch-querier disabled
- Querier address was previously configured on another switch.
Workaround
Configure the IGMP querier configuration with a different IP address.
