Can some one give me a reason why I can trigger beaucoup ICMP messages on an ethernet with just one measly icmp packet? Configuration: GW for 192.5.16 (subnets 192.5.16.32 and | 192.5.16.64, mask = 255.255.255.224) 128.165.4.16 | ============================================================= | | | | 128.165.4.10 128.165.4.4 route (192.5.16 128.165.4.16 UG ...) Scenario: 128.165.4.10 sends exactly one icmp echo to 192.5.16.1 192.5.16.1 is a bogus hostname on an undefined subnet. 128.165.4.4 sends 100* ICMP packets to 128.165.4.10 with a 'redirect for network to 128.165.4.16' 128.165.4.10 sends 128* ICMP 'echo' packets to 192.5.16.1 (via 128.165.4.16) Remember the 'ping' program only sent ONE icmp echo packet. * these are the numbers I observed. There could have been more. Thanks for your consideration, Phil Wood, cpw@lanl.gov
