    Setting a TTL Value for the IP Header

    You set the time-to-live (TTL) field in the IP header for all IP operations using the ip ttl command. The TTL specifies a hop count. This configured TTL value can be overridden by other commands that specify a TTL.

    To set the value for the TTL field:

    • Issue the ip ttl command in Global Configuration mode.
      host1(config)#ip ttl 255

      Use the no version to restore the default value, 127.
