Routers *do* strip the source and destination MAC addresses (and any 
other layer 2 specific information) when forwarding an IP packet. If 
applicable, the source MAC address is replaced by the MAC address of the 
router output interface and the destination MAC address is replaced by 
the next hop interface MAC address. That's what I meant when saying that 
layer 2 information is not routed.
