v20 v21 699 699 The Mesoscale deployment can offer different topologies for communicating between hosts. We have provisioned two different subnets in the Mesoscale infrastructure, each using a different VLAN (one using 3715 and the other 3716). 700 700 701 The two subnets that have been provisioned are '''10.42.144.0/24''' on 3715 and 702 '''10.42.149.0/24''' on 3716. 701 The two subnets that have been provisioned are '''10.42.144.0/24''' on 3715 and '''10.42.149.0/24''' on 3716. 703 702 704 703 First of all let's see how we can figure out the IP of the hosts we reserved : … … 721 720 * Figure out the last octet of the IP address of your hosts. The way these MyPLC hosts are setup, is that they have multiple subinterfaces, each configured to be part of a different IP subnet. Almost all subnets in the hosts are in the form of 10.42.Y.0/24. You will notice that for all these subnets, your host has the same last octet. In the example above all the subinterfaces of eth1, will have an IP address that will end in '''90''' (10.42.147.'''90''', 10.42.148.'''90''') 722 721 723 * Ping over 3715. After loging in to your hosts ping from host1 to host2. 724 Assuming that host2 has a last octet of YYY you should: 725 722 * Ping over 3715. After logging in to your hosts, ping from host1 to host2. Assuming that host2 has a last octet of YYY you should: 726 723 {{{ 727 724 ping 10.42.144.YYY … … 729 726 Notice the RTT on the packets. 730 727 731 * Ping over 3716. After loging in to your hosts ping from one host2 to host1. 732 Assuming that host1 has XXX as it's last octet you should ping 733 728 * Ping over 3716. After logging in to your hosts, ping from one host2 to host1. Assuming that host1 has XXX as it's last octet you should ping 734 729 {{{ 735 730 ping 10.42.149.XXX 736 731 }}} 737 Notice the RTT on the packets and compare it with the above ping.732 * Notice the RTT on the packets and compare it with the above ping. 738 733 739 734 = III. Run a Layer 2 Experiment = 740 735 741 The mesoscale GENI resources are connected on Layer 2, which enables Layer 2, i.e. non-IP experiments. In this exercise we are going 742 to run a layer 2 ping program, where we are going to send raw Ethernet frames of a custom Ethernet type to a server and receive a reply. 743 Currently MyPLC only supports IP experiments, so we will use our ProtoGENI host which we have reserved in the beginning. 736 The mesoscale GENI resources are connected on Layer 2, which enables Layer 2, i.e. non-IP experiments.
