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.
