Purpose
Command or Action
(Optional) Prevents PIM dense mode fallback.
no ip pim dm-fallback
Step 14
Example:
Device(config)# no ip pim dm-fallback
•
Skip this step if all interfaces have been configured to operate in
PIM sparse mode.
The
no ip pim dm-fallback
command behavior is enabled by
default if all the interfaces are configured to operate in PIM
sparse mode (using the
ip pim sparse-mode
command).
Note
Selects an interface that is connected to hosts on which PIM can be
enabled.
interface type number
Example:
Device(config)# interface
gigabitethernet 1/0/0
Step 15
Configures an administratively scoped boundary.
ip multicast boundary access-list
[
filter-autorp
]
Step 16
•
Perform this step on the interfaces that are boundaries to other
devices.
Example:
Device(config-if)# ip multicast
boundary 10 filter-autorp
•
The access list is not shown in this task.
•
An access list entry that uses the
deny
keyword creates a multicast
boundary for packets that match that entry.
Returns to global configuration mode.
end
Example:
Device(config-if)# end
Step 17
(Optional) Displays the Auto-RP information.
show ip pim autorp
Example:
Device# show ip pim autorp
Step 18
(Optional) Displays RPs known in the network and shows how the device
learned about each RP.
show ip pim rp
[
mapping
] [
rp-address
]
Example:
Device# show ip pim rp mapping
Step 19
(Optional) Displays the multicast groups having receivers that are directly
connected to the device and that were learned through Internet Group
Management Protocol (IGMP).
show ip igmp groups
[
group-name
|
group-address
|
interface-type
interface-number
] [
detail
]
Step 20
Example:
Device# show ip igmp groups
•
A receiver must be active on the network at the time that this
command is issued in order for receiver information to be present
on the resulting display.
