PIM Dense
1
1. If more than one device has the same DR priority on a subnet (as in the case of default DR
priority on all), the device with the numerically highest IP address on that subnet is elected as
the DR.
2. The DR priority information is used in the DR election ONLY IF ALL the PIM devices connected
to the subnet support the DR priority option. If there is at least one PIM device on the subnet
that does not support this option, then the DR election falls back to the backwards
compatibility mode in which the device with the numerically highest IP address on the subnet
is declared the DR regardless of the DR priority values.
Displaying basic PIM Dense configuration

Brocade(config)#
Syntax: show ip pim [vrf vrf-name] dense
The vrf option allows you to display PIM dense configuration information for the VRF instance
identified by the vrf-name variable.
This display shows the following information.
This field... Displays...
Maximum Mcache The maximum number multicast cache entries allowed on the device.
Current Count The number of multicast cache entries currently used.
Hello interval How frequently the device sends hello messages out the PIM dense
interfaces.
Neighbor timeout The interval after which a PIM device will consider a neighbor to be
absent.
Graft or Retransmit interval How interval between the transmission of graft messages.
Inactivity interval How long a forwarding entry can remain unused before the device
deletes it.
