MLD-Proxy IF Flap Discredit
MLD IF is MLD Proxy-enabled upstream or downstream interface that is used for MLD
proxy implementation.
MLD IF flap discredit function has been designed to minimize such a path recalculation
caused by the IF flapping, which can increase the stability and quality for multicast ser-
vice. Using this function, the V8102 gives a discredit to a MLD IF for every flapping time,
and then the IF is not selected as a forwarding path until its credit is regenerated.
MLD Proxy IF flap discredit function is implemented with the following restrictions, so you
must keep them in mind before setting the related commands or parameters.
•
If you configure recover-interval value as 0, the decreased MLD IF credit is not re-
covered.
•
If the credit unit becomes 0 because of the continuous flapping of MLD IF, the
credit is not recovered until
clear ipv6 mld if flap discredit
command is configured.
To enable/disable the MLD IF flap discredit function, use the following command.
Command
Mode
Description
ipv6 mld if flap discredit
Global
Enables the MLD IF flap discredit. (default)
no ipv6 mld if flap discredit
Disables the MLD IF flap discredit.
To specify the discredit value in case of MLD IF flapping, use the following command.
Command
Mode
Description
ipv6 mld if flap discredit unit
<1-
50>
Global
Specifies the discredit value for the IF flapping and
decreases the credit unit as much as a specified value.
(default: 5)
no ipv6 mld if flap discredit unit
Deletes a configured discredit value.
To set the MLD IF flap credit regenerating rate, use the following command.
Command
Mode
Description
ipv6 mld if flap recover-interval
<0-3600>
Global
Specifies the interval of recovering its credit as much
as a specified value. (default: 10 seconds)
ipv6 mld if flap recover-unit
<1-
50>
Sets the regenerating value of the IF credit.
(default: 5)
no ipv6 mld if flap
{
recover-
interval
|
recover-unit
}
Deletes a configured IF credit regenerating rate.
If you configure this rate as 0, the MLD IF credit is not regenerated!
To set the current MLD IF credit as the default (100), use the following command.
