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, HP does not recommend
this method of checksum calculation.
SSM policy
Configure the SSM group range.
Whether the PIM-SSM model or the PIM-SM model delivers the information from
a multicast source the receivers depends on whether the group address in the
(S, G) packets that the receivers request is in the SSM group range. All
PIM-SM-enabled interfaces assume the PIM-SSM model for multicast groups
within this address range.
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 Configuation Guide..
If you do not click the box, 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.
