## Symptoms

- * Multicast streams are not forwarded through specific interfaces of the Security Gateway.

* The IGMP querier does not send "General Query" packets to multicast group 224.0.0.1 every Query Interval (the default is 125 seconds).

* The output of Clish command "*show igmp interfaces*" shows that the "Next Membership Query" will be in over a year.

  *Example* :

  ```
  
  HostName> show igmp interfaces
  IGMP Interface State
  
  Interface eth1-05.89
      Flags:                         Querier
      IGMP Version:                  2
      Loss Robustness:               2
      Query Interval:                125
      Query Response Interval:       10
      Last Member Query Interval:    1
      Multicast Protocol(Instance):  PIM(0)
      Advertise Address:             59.0.0.101
      Number Group Joins:            517
      Number Group Active:           158
      Next Membership Query:         4286716047
      Querier Up Time:               31289116
  ```

* Rebooting the Security Gateway resets the "Next Membership Query" timer.

  *Example* :

  ```
  
  HostName> show igmp interfaces
  IGMP Interface State
  
  Interface eth1-05.89
      Flags:                         Querier
      IGMP Version:                  2
      Loss Robustness:               2
      Query Interval:                125
      Query Response Interval:       10
      Last Member Query Interval:    1
      Multicast Protocol(Instance):  PIM(0)
      Advertise Address:             59.0.0.1
      Number Group Joins:            8
      Number Group Active:           7
      Next Membership Query:         12
      Querier Up Time:               500
  ```

* Setting up a new IGMP querier on the network resolves the issue.

## Cause

The RouteD daemon miscalculates the Querier's "Next Membership Query" value.
