ADSL动态双网关问题

beyonddai

各位：我想设多网关，想如下设置：
/ip route add dst-address=0.0.0.0/0 gateway=3.3.3.3 comment="test" disabled=no
我想改成双网关下面的语句可以
/ip route set[/ip route find comment=test] gateway=1.1.1.1,2.2.2.2
可是用参数就不行，如下
:local new-addressa
:local new-addressb
:set new-addressa=1.1.1.1
:set new-addressb=2.2.2.2
/ip route set[/ip route find comment=test] gateway=$new-addressa,$new-addressb
上面的语句就无法运行，我试过gateway=$new-addressa是可以的，加逗号和第二个变量就不行了，请高手赐教
