no ip pim register-suppression
Deletes the specified the registration suppression time.
Register Message Filtering
You can enable the router to filter multicast sources specified in access lists at the RP.
This filtering will permit/deny the PIM register messages for the specified sources. If
unauthorized sources try to register with the RP, the RP then drops the PIM register
messages from those sources. You can specify the either multicast source or source’s DR
address in access lists.
To enable the router to filter multicast sources, use the following command.
ip pim accept-register list {<100-
199> | <2000-2699> | WORD}
Enables the router to filter multicast sources.
100-199: IP extended access list
2000-2699: IP extended access list (extended range)
WORD: access list name
no ip pim accept-register
Disables the router to filter multicast sources.
RP Reachability Validation
To enable the RP reachability validation for the source registration process at the first-hop
router, use the following command.
ip pim register-rp-reachability
Enables the RP reachability validation.
no ip pim register-rp-reach-
ability
Disables the RP reachability validation. (default)
Source Address of Register Message
You can specify the source IP address of PIM register messages sent by the DR. This
address is used to send corresponding PIM register-stop messages in response. By
default, the source address of register messages is the IP address of the interface toward
the RP. This address must be able to be learned by unicast routing protocols on the DR.
To specify the source IP address of PIM register messages, use the following command.
ip pim register-source {A.B.C.D |
INTERFACE}
Specifies the source IP address of register messages.
A.B.C.D: source IP address
INTERFACE: interface name
no ip pim register-source
Deletes a specified source IP address of register
messages.
9.3.3.4 SPT Switchover
PIM-SM provides the switching option to deliver multicast traffic on the SPT. Multicasting
over the SPT may be more efficient than multicasting over the RPT, since it can
