/tool traffic-generator packet-template
add header-stack=mac,ip,udp ip-dst=2.2.2.1/32 ip-gateway=1.1.1.2 ip-src=1.1.1.1/32 \
name=routing-1 port=port0
add header-stack=mac,ip,udp ip-dst=1.1.1.1/25 ip-gateway=2.2.2.2 ip-src=2.2.2.1/32 \
name=routing-2 port=port1
Notice that mac addresses was not specified since template generator can assume next-hop mac address
automatically by sending ARP messages. Since we are doing routing and destination IP is not directly reachable, we
have set ip-gateway parameter to determine next-hop mac-address.
When running print you can see all assumed (detected) values including mac addresses.
[admin@test-host] /tool traffic-generator packet-template> print

For example if any router in SUT change, assumed mac-addresses will not be updated automatically. To update
packet templates simply issue command :
/tool traffic-generator packet-template set [find]
Last part is to configure streams
/tool traffic-generator stream
add disabled=no mbps=500 name=str1 num=3 packet-size=1450 port=port0 pps=0 \
tx-template=routing-1
add disabled=no mbps=500 name=str3 num=4 packet-size=1450 port=port1 pps=0 \
tx-template=routing-2
Notice that each stream has unique num value. This value identifies stream packets, otherwise traffic generator will
not work.
Now we are ready to run the test. In this case quick mode will be used:
[admin@test-host] /tool traffic-generator> quick mbps=450
