Distinguish MPLS switched traffic from IP routed traffic.

Hello comunity,

I am looking for commands to distinguish wether traffic is routed via IP header lookup or switched via MPLS Fwd. Table lookup. ALl the routers are cisco IOS based.

Green lines are interfaces with IS-IS and MPLS enabled. Black lines are IP only interfaces. Host prefixes are advertised via BGP. No Vrfs are used.

​

My question is, how can i simply distinguist wether the traffic between particular hosts is being routed or switched.

Thanks.
