This example (provided originally by Jasmy Azry B. Johari from Telekom Malaysia) shows a two-hosts simulation. There are two host (A and B), connected throught a network segment (eth1 interface in both host). One VNUML specification (umlA.xml) is built in host A and a second VNUML specification (umlB.xml) is built in host B. Each piece of simulation is based on the [../basic/basic.html VNUML basic example].Note the use of offset="1" in the <automac> tags in umlB.xml, to avoid umlA3 and umlB3 have the same MAC address in Net3.The example assumes that both hosts are connected using the eth0 in both cases.
hostA# vnumlparser.pl -t umlA.xml -v ... hostB# vnumlparser.pl -t umlB.xml -v
Traceroute traces (umlB5 -> umlA5 and umlA1 -> umlB5):
