word by word from Beau's book "Query Interval timer---This timer was changed to 125 seconds. Early implementations used a value of 60 seconds. This discrepancy can cause a problem when a router with an early implementation is operating on the same LAN as a router that is the IGMP Querier and is IGMPv2 compliant. In this case, the early implementation router may believe erroneously that the IGMP Querier (the IGMPv2-compliant router) has gone down because the General Queries are 125 seconds apart."
