On a Cisco-router: router#ping 10.60.200.1 size 100 repeat 1 Type escape sequence to abort. Sending 1, 100-byte ICMP Echos to 10.60.200.1, timeout is 2 seconds: ! Success rate is 100 percent (1/1), round-trip min/avg/max = 16/16/16 ms On the wire: 09:36:11.497266 vlan 160, p 0, IP (tos 0x0, ttl 255, id 34, offset 0, flags [none], proto ICMP (1), length 100) 10.60.200.236 > 10.60.200.1: ICMP echo request, id 10, seq 0, length 80 The 100 Byte packet length in the ping command results in a 100 Byte IP-packet, so clearly it *includes* IP and ICMP headers. -- Per Carlson _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
