no version of the command removes the neighbor filtering applied on that interface, if any. It is not
mandatory to provide Access-list name or number as at most only one ACL can be applied per
interface.
Displaying show command
These commands will display the configuration.
Brocade(config)#show run

interface ethernet 1/3

ip address 10.10.10.1/24
ip pim-sparse
ip pim neighbor-filter 10
ipv6 address a100:1111::9/64
ipv6 pim-sparse
ipv6 pim neighbor-filter f10
………
The show ip|ipv6 pim interface now incorporates the Filter ACL information field as well.
On turning on debug ip pim nbr-change on a PIM-enabled interface, the debug messages analyze
that Hello packets are received from the neighbor. On applying the neighbor-filter for the sender on
that interface, the Hello packets are still received but are instantly dropped thereby preventing the
sender host to become a PIM neighbor on that interface.

PIM Sparse
Brocade devices support Protocol Independent Multicast (PIM) Sparse version 2. PIM Sparse
provides multicasting that is especially suitable for widely distributed multicast environments. The
Brocade implementation is based on RFC 2362.
In a PIM Sparse network, a PIM Sparse device that is connected to a host that wants to receive
information for a multicast group must explicitly send a join request on behalf of the receiver (host).
PIM Sparse devices are organized into domains. A PIM Sparse domain is a contiguous set of
devices that all implement PIM and are configured to operate within a common boundary.
shows a simple example of a PIM Sparse domain. This example shows three devices configured as
PIM Sparse devices. The configuration is described in detail in the following figure.
