Item Description
Auto-RP
Enable or disable auto-RP.
IMPORTANT:
Auto-RP announcement and discovery messages are addressed to the multicast group
addresses 224.0.1.39 and 224.0.1.40 respectively. With auto-RP enabled on a device,
the device can receive these two types of messages and record the RP information
carried in such messages.
Register checksum
Calculate the register message checksum based on the entire register messages or the
header parts.
IMPORTANT:
In view of information integrity of register messages in the transmission process, you can
configure the device to calculate the checksum based on the entire register messages.
However, to reduce the workload of encapsulating data in register messages and for the
sake of interoperability, H3C does not recommend this method of checksum calculation.
SSM policy
Configure the SSM group range.
You can define the multicast group range by selecting the box and specifying the ACL.
If a group address falls into the SSM group range, multicast data is delivered based
on the PIM-SSM model. Otherwise, it is delivered based on the PIM-SM model.
Click Select to enter the page displaying the existing basic ACLs. Select an ACL as
needed and click Back to finish the operation and return to the PIM advanced
configuration page. In addition, in the basic ACL displaying page, you can add,
modify, or delete a basic ACL, or configure ACL acceleration for the ACL. For more
information, see Access Control Configuration Guide.
If the box is not selected, the SSM group range is 232.0.0.0/8, no matter an ACL is
specified or not.
IMPORTANT:
• Make sure the same SSM group range is configured on all devices in the entire
domain. Otherwise, multicast information cannot be delivered through the SSM
model.
• When a member of a multicast group in the SSM group range sends an IGMPv1 or
IGMPv2 report message, the device does not trigger a (*, G) join.
Displaying PIM neighbor information
