t he rout er connect ed t o t he upst ream port . This value should be exact ly t he sam e as
what 's configured in t he connect ed m ult icast rout er.
This value is used t o calculat e t he am ount of t im e an MLD snooping m em bership

When an MLD Report m essage is received, t he Swit ch set s t he t im eout period of t he
ent ry t o be T = ( QI * RV) + MRD, where T = Tim eout , QI = Query I nt erval, RV =
Robust ness Variable, and MRD = Maxim um Response Delay.
