I don't think you can capture packets destined for lo0 from other boxes, as they enter the router through an other interface and is forwarded to the Routing-Engine directly, they will never enter or be be sent out on lo0. The only traffic seen on lo0, would be localy generated traffic destined to lo0. For example if you ping 127.0.0.1 or some other lo0-address from the local router. So to capture traffic destined for lo0, you will have to capture the traffic on the incoming/outgoing interface. Where you can match on the addresses of lo0, if you want. Note that you will never capture traffic transiting the router, as those pakets never reaches the RE.
