MAC addresses are not globally unique. The router can happily use the same
MAC address for each interface as long as it keeps track of which interface
it receives a packet addressed to itself on...
Typically LAN interfaces have unique MAC address (unique to the router)
whilst the serial interface 'borrows' the lowest MAC address on the router
for its packets addressing requirements.
