Cisco Catalyst 3650 User Manual

•
Before configuring PIM stub routing, you must have IP multicast routing configured on both the stub
router and the central router. You must also have PIM mode (dense-mode, sparse-mode, or
sparse-dense-mode) configured on the uplink interface of the stub router.
•
Before configuring PIM stub routing, you must also configure either Enhanced Interior Gateway Routing
Protocol (EIGRP) stub routing or Open Shortest Path First (OSPF) stub routing on the device. The PIM
stub router does not route the transit traffic between the distribution routers. Unicast (EIGRP) stub
routing enforces this behavior. You must configure unicast stub routing to assist the PIM stub router
behavior.
For information about EIGRP or OSPF configurations, see the Catalyst 3650 Routing
Configuration Guide, Release 3SE.
Note
Restrictions for Configuring PIM
The following are the restrictions for configuring PIM:
•
PIM
◦
PIM is not supported when running the LAN Base feature set.
•
PIM stub routing
◦
The IP Services image contains complete multicast routing.
◦
In a network using PIM stub routing, the only allowable route for IP traffic to the user is through
a device that is configured with PIM stub routing.
◦
The redundant PIM stub router topology is not supported. Only the nonredundant access router
topology is supported by the PIM stub feature.
◦
Only directly connected multicast (IGMP) receivers and sources are allowed in the Layer 2 access
domains. The PIM protocol is not supported in access domains.
Restrictions for Configuring Auto-RP
The following are restrictions for configuring Auto-RP (if used in your network configuration):
•
Auto-RP is not supported when running the LAN Base feature set.
•
If you configure PIM in sparse mode or sparse-dense mode and do not configure Auto-RP, you must
manually configure an RP.
•
If routed interfaces are configured in sparse mode, Auto-RP can still be used if all devices are configured
with a manual RP address for the Auto-RP groups.
•
If routed interfaces are configured in sparse mode and you enter the ip pim autorp listener global
configuration command, Auto-RP can still be used even if all devices are not configured with a manual
RP address for the Auto-RP groups.
