Configuring Mdt Switching Parameters - HP A8800 Configuration Manual

Configuration procedure
Perform the following configuration on the PE.
To configure a share-group and an MTI binding:
Step
1. Enter system view.
2. Enter VPN instance view.
3. Configure a share-group
address and an MTI binding.

Configuring MDT switching parameters

To avoid frequent switching of multicast traffic between the share-MDT and the switch-MDT:
An MDT switchover does not take place immediately after the multicast traffic forwarding becomes stable,
but it takes place after a switch-delay period has passed, during which the multicast traffic keeps being
forwarded.
Perform the following configuration on the PE.
To configure MDT switching parameters:
Step
1. Enter VPN instance view.
2. Configure the address range
of the switch-group-pool.
3. Configure the switch-delay
period.
Enabling switch-group reuse logging
For a given VPN, if the number of private network multicast streams to be switched to switch-MDTs
exceeds the number of addresses in the switch-group-pool, the VPN instance on the source-side PE device
can reuse the addresses in the address pool. By enabling the switch-group reuse logging function, you
can have the address reuse information logged.
Attributed to the MD module, the group address reuse logging information has a severity level of
informational. For more information about the logging information, see Network Management and
Monitoring Configuration Guide.
With switch-group reuse logging enabled, the generated group address reuse logging information will
be sent to the information center, where you can configure the rules for outputting the logging information.
For more information about the configuration of the information center, see Network Management and
Monitoring Configuration Guide.
Perform the following configuration on the PE.
