PIM6 SM traffic snooping is disabled.
VLAN configuration mode
The device must be in multicast listening discovery (MLD) passive mode before it can be configured for PIM6 sparse mode (SM) snooping.
When PIM6 SM snooping is enabled globally, you can override the global setting and
disable it for a specific VLAN. You must configure the
multicast6 disable-pimsm-snoop command to disable PIM6 SM snooping on a VLAN.
A smaller prune wait value reduces flooding of unwanted traffic. A prune wait value of zero causes the PIM device to stop traffic immediately upon receiving a prune message. If there are two or more neighbors on the physical port, then the prune-wait option should not be used because one neighbor may send a prune message while the other sends a join message at the same time, or within less than five seconds.
The
no form of this command without options disables PIM6 SM traffic snooping on a VLAN.
The
no form of the command with the
prune-wait option resets the prune-wait time as 5 seconds.
The following example first configures VLAN 20 and adds the ports that are connected to the device and host in the same port-based VLAN . Then it enables MLD snooping passive on VLAN 20 and enables PIM6 SM traffic snooping on it. The prune-wait timer is set as 10 seconds.
