运行测试例

在 /p4-rt/PI/ 目录下运行:

simple_switch tests/testdata/simple_router.json  // to start the switch
./CLI/pi_CLI_bmv2 -c tests/testdata/simple_router.json  // to start the CLI
PI CLI> assign_device 0 0 -- port=9090  // 0 0 : device id + config id
PI CLI> table_add ipv4_lpm 10.0.0.1/24 => set_nhop 10.0.0.1 1
PI CLI> table_dump ipv4_lpm
PI CLI> table_delete ipv4_lpm <handle returned by table_add>
