Default-Group - HP 5900 Series Command Reference Manual

Predefined user roles
network-admin
Parameters
group-address: Specifies a multicast group address in the range of 224.0.1.0 to 239.255.255.255.
mask-length: Specifies an address mask length in the range of 25 to 32.
mask: Specifies the address mask.
acl acl-number: Specifies an advanced ACL number in the range of 3000 to 3999. I f you specify an ACL,
the configured MDT switchover criteria applies to the (S, G) entries that the ACL permits. If you do not
specify an ACL, the configured MDT switchover criteria apply to all (S, G) entries. To make the ACL
effective, specify the protocol type as IP, and include the source and destination keywords when creating
an ACL rule. The source and destination keywords specify a multicast source address range and a
multicast group address range, respectively.
Usage guidelines
On a PE device, the data-group address range must meet the following requirements:
It must not include the default-group address of the MD.
•
It must not overlap with the data-group address range of any other MDs.
•
On different devices, if the public network is not in PIM-SSM mode, the data-group address ranges for
different MDs cannot overlap.
If you execute the command multiple times in an MD, the most recent configuration takes effect.
If you configure this command on the device, switchover from the default-MDT to data-MDT will take
place when the following conditions are met:
The device receives the multicast traffic that has passed the ACL rule filtering.
•
• The multicast traffic is maintained for the data-delay period.
