The default datagram packet size is 64 bytes, or you can specify a size with the packetsize command-line argument. If an optional count is specified, ping sends ping requests until it either sends count requests or receives count replies. When using ping for fault isolation, first ping the local host to verify that the local network interface is running. Use this option in the IP header to send the packet to the given host and back again. Usually specified with the - R option.
L Turn off loopback of multicast packets.
Normally, if there are members in the host group on the outgoing interface, a copy of the multicast packets will be delivered to the local machine. If the host is not on a directly-attached network, an error is returned. Sets the IP record route option, which will store the route of the packet inside the IP header. Specify the interval between successive transmissions. The default is one second.
