Keywords: subnet IP ICMP fnord Message-ID: Date: 8 Nov 90 14:13:38 GMT Sender: news@nixpbe.nixdorf.de Lines: 18 This might be a silly question, but it's been worrying me for some time. What happens if different IP subnets live on the same ethernet cable? I'm worried about excessive ICMP traffic (ICMP net_redirect packets); I see some SGI workstations here react to some packets from a different subnet with this ICMP message. Could somebody tell me if this is a problem or what other problems I haven't even thought of might arise? Pointers to books, RFCs etc. on this subject are also welcome.
