Very often customers or NMS send ICMP "echo request" packages to a router physical interface, subinterface or loopback interface and expect ICMP "echo reply" as a response in order to test packet loss on the connection. How reliable are Juniper routers in terms of replying to ICMP "echo request" packages? As far as I know, ICMP traffic gets software based handling and thus delay of the ICMP "echo reply"(or if there is a reply sent at all) depends on the load of the CPU. Does this depend on specific router model? Or has this more to do with interface type? Can one prioritized/de-prioritized ICMP generation under JUNOS?
PS many questions, but an exhaustive discussion on this topic would be nice :) regards, martin _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
