Disabling Rpt-To-Spt Switchover; Configuring Common Pim Parameters - H3C S5600 Series Operation Manual

Operation Manual – Multicast
H3C S5600 Series Ethernet Switches
Configure to filter the
registration packets
from RP to DR
Caution:
Only the registration packets matching the permit command of ACLs can be accepted.
When an invalid ACL is defined, RP will reject all the registration packets.

4.3.5 Disabling RPT-to-SPT Switchover

Initially, a PIM-SM-enabled multicast device forwards multicast packets through an RPT.
By default, the last-hop switch initiates an RPT-to-SPT switchover process. You can
also disable RPT-to-SPT switchover through the configuration.
Follow these steps to disable RPT-to-SPT switchover:
Enter system view
Enter PIM view
Disable RPT-to-SPT
switchover
Note:
Typically, you need to configure the above-mentioned parameters on the receiver-side
DR and the RP only. Since both the DR and RP are elected, however, you should carry
out these configurations on the routers that may win DR election and on the C-RPs that
may win RP election.
