Rate Limiting ICMPv4 and ICMPv6 Traffic

 

To limit the rate at which ICMPv4 or ICMPv6 messages can be generated by the Routing Engine and sent to the Routing Engine, include the appropriate rate limiting statement at the [edit system internet-options] hierarchy level:

  • For IPv4:

    • icmpv4-rate-limit bucket-size bucket-size packet-rate packet-rate

  • For IPv6:

    • icmpv6-rate-limit bucket-size bucket-size packet-rate packet-rate

The bucket size is the number of seconds in the rate-limiting bucket. The packet rate is the rate-limiting packets earned per second. Specify a bucket-size from 0 through 4294967295 seconds. The default value is 5 seconds. Specify a packet-rate from 0 through 4,294,967,295. The default value is 1000.
