Displaying And Debugging Pim; Configuring The Threshold At Which The Shared Tree Is Switched To The Spt - Huawei Quidway S3900 Series Operation Manual

Operation Manual – Multicast Protocol
Quidway S3900 Series Ethernet Switches-Release 1510
Operation
Configure to filter the
registration packets from
RP to DR
Caution:
If a source group entry (S, G) is denied in ACL, or no operation on the entry is
defined in the ACL, or ACLs are not defined, RP will send RegisterStop messages
to DR to stop the registration process of the multicast data flow.
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.
7.4.5 Configuring the Threshold at Which the Shared Tree is Switched to the
SPT
In PIM-SM, Ethernet switches forward multicast packets through the shared tree at the
beginning. If the threshold is set to 0, the Ethernet switch at the last hop of multicast
packets will switch the shared tree to the SPT
Table 7-11 Set the threshold at which the shared tree is switched to the SPT
Operation
Enter system view
Enter PIM view
Set the threshold at
which the shared tree is
switched to the SPT
