![]() This comprehensive guide will explain everything you need to know about the causes of. ![]() Packet loss sits in the trio of two other major network performance complications: latency, and jitter. In addition, check the subnet mask to ensure that a remote address has not been interpreted as a local address. Packet loss occurs when network congestion, hardware issues, software bugs, and a number of other factors cause dropped packets during data transmission. If the remote routing tables are correct and contain a valid route back to the sending host, use the arp -a command to determine whether the correct address is listed in the ARP cache. ![]() Most often, it indicates that a route back to the sending host has failed, because the destination host, one of the intermediary routers, or the default gateway of the destination host does not recognize the route back to the sending host.Ĭheck the routing table of the destination host to determine whether it has a route to the sending host before checking the routing tables of the individual routers. This message may be the result of network congestion, failure of the ARP request, packet filtering, a routing error, or a silent discard. Indicates that no “Echo Reply” messages were received within the default time of one second. Sorry I don’t have time to research further, but Help in 2000 + Microsoft Knowledge Base should be able to provide the rest of what you need to do. I think you may have a packet filtering problem. Where am I going wrong? Is there a step I have skipped? Any insight/help is appreciated.I got this from my MCSE course material. When I try pinging h2 from h1 and vice versa I get destination host unreachable error. I am trying to setup the experimental topology such that both the hosts can access each other, which of course, is possible through configuring routing tables The router r2 has the following configuration: lo: flags=6 The router r1 has the following config: lo: flags=6 The host Machine 'h2' has the following config: h2-eth0: flags=41 TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 The host Machine 'h1' has the following configuration: h1-eth0: flags=41 As a part of an experiment, my network has the following topology for two host machines connected to a router in mininet(on Ubuntu 22.04.02 Virtual Machine) h1 - r1 - r2 - h2
