Configuring PIM-SM
Fixed Switch Configuration Guide 19-21
Refer to the device’s CLI Reference Guide, as applicable, for an example of each command’s output.
Configuring PIM-SM
PIM-SM is an advanced routing feature that must be enabled with a license key.
Design Considerations
Enterasys Networks recommends that administrators consider the following recommendations
before configuring the fixed switch platforms for a PIM-SM environment.
• A fixed switch device cannot be configured as a Candidate-RP or a Candidate-BSR.
• A fixed switch device should not be the first hop router for a multicast stream. In other words,
the multicast stream should not originate on a fixed switch device.
• A fixed switch device should not be positioned in the core of a PIM-SM topology, and should
only be positioned at the edge in a PIM-SM topology. In other words, the fixed switch device
should only be used to deliver multicast streams to end clients.
PIM-SM Configuration Commands
Table 19-9 lists the PIM-SM set commands for stackable and standalone devices that support and
have enabled advanced routing.
Table 19-8 DVMRP Show Commands
Task Command
Display DVMRP routing information, neighbor
information, or DVMRP enable status.
show ip dvmrp [route | neighbor | status]
Display the IP multicast routing table. show ip mroute [unicast-source-address |
multicast-group-address] [summary]
Table 19-9 PIM-SM Set Commands
Task Command
Set the administrative mode of PIM-SM multicast
routing across the router to enabled. By default,
PIM-SM is globally disabled. Use the no command
to disable PIM (across the entire stack, if applicable).
ip pimsm
no ip pimsm
Create a manual RP IP address for the PIM-SM
router. Use the no command to remove a previously
configured RP.
ip pimsm staticrp ipaddress groupaddress
groupmask
no ip pimsm staticrp ipaddress groupaddress
groupmask
Enable PIM-SM multicast routing on a routing
interface. By default, PIM is disabled on all IP
interfaces. Use the no command to disable PIM on
the specific interface.
ip pimsm enable
no ip pimsm enable
Configure the transmission frequency of hello
messages, in seconds, between PIM-enabled
neighbors. Use the no command to reset the hello
interval to the default, 30 seconds.
ip pimsm query-interval seconds
no ip pimsm query-interval
