This object defines the time window (in seconds) used to rate-limit ICMPv6 'time exceeded' messages sent from a virtual router interface, preventing message flooding during network loops or TTL exhaustion events. When the configured time interval expires, the rate limiter resets to allow a new burst of such messages. An operator adjusts this value to balance diagnostic feedback with network stability when preventing ICMP rate-limit attacks or managing high-latency path discovery.
