10.1.2 MLD Querier’s Robustness Variable
You can statically configure the Querier’s Robustness Variable (QRV) field in the query
message. The MLD QRV allows tuning for the expected packet loss on a network. If a
network is expected to be lossy, the QRV value may be increased. When receiving the
query message that contains a certain QRV value from a querier, a host returns the report
message as many as the specified QRV value.
To configure the QRV value on an interface, use the following command.
Command
