This read-write integer sets the timeout, in seconds and ranging from 300 to 9999999, after which a dynamically learned EZ2Route host entry is aged out if inactive. An admin tunes this based on how long hosts on the network typically stay connected before disconnecting or changing addresses, balancing table freshness against unnecessary relearning. For example, in a network with mostly stable desktop hosts, an admin might raise this timeout well above the 300-second minimum to avoid needlessly forgetting hosts that are just briefly idle.
