Displaying multicast neighbor information
To display information about IPv6 PIM neighbors, enter the show ipv6 pim neighbor command at
any CLI level.
Syntax: show ipv6 pim [vrf vrf-name] neighbor
The vrf parameter allows you to display the IPv6 PIM neighbors for the VRF instance identified by
the vrf-name variable.
Table 39 displays the output from the show ipv6 pim neighbor command.
Displaying the IPv6 PIM multicast cache
To display the IPv6 PIM multicast cache, enter the show ipv6 pim mcache command at any CLI
level.
NOTE
Brocade NetIron CES and NetIron CER devices display incorrect hardware programmed entries. The
information displayed for the forwarding port should be disregarded.

TABLE 39 Output from the show ipv6 pim neighbor command
Field Description
Port The interface through which the device is connected to the neighbor.
Neighbor The IPv6 interface of the IPv6 PIM neighbor interface.
Holdtime sec Indicates how many seconds the neighbor wants this device to hold the entry for this neighbor
in memory. The neighbor sends the Hold Time in its hello packets.
•
If the device receives a new hello packet before the Hold Time received in the previous
packet expires, the device updates its table entry for the neighbor.
•
If the device does not receive a new hello packet from the neighbor before the Hold time
expires, the device assumes the neighbor is no longer available and removes the entry
for the neighbor.
Age sec The number of seconds since the device received the last hello message from the neighbor.
UpTime sec The number of seconds the PIM neighbor has been up. This timer starts when the device
receives the first hello messages from the neighbor.
Priority The DR priority that is used in the DR election process. This can be a configured value or the
default value of 1.
