with RP or
• If non directly connected source passed source RPF check.
In PIM-DM
• The route has no OIF and
• passed source RPF check and
• Router has no downstream PIM neighbor.
If the OIF is inserted after the hardware-drop entries are installed, the hardware entries will be
updated to include the OIFs.
NOTE
Disabling hardware-drop does not immediately take away existing hardware-drop entries, they will
go through the normal aging processing when the traffic stops.
Configuring PMRI
PMRI is enabled by default. To disable PMRI, enter commands such as the following.
BigIron RX(config)#router pim
BigIron RX(config-pim-router)#hardware-drop-disable

Changing IGMP V1 and V2 parameters
IGMP allows Brocade routers to limit the multicast of IGMP packets to only those ports on the
router that are identified as IP Multicast members.
The router actively sends out host queries to identify IP Multicast groups on the network
The following IGMP V1 and V2 parameters apply to PIM and DVMRP:
• IGMP query interval – Specifies how often the BigIron RX queries an interface for group
membership. Possible values are 1 – 3600. The default is 125.
