Layer 3 switch = Router (IMHO) esp in today's world. All layer 3 switches
that are routing packets using layer 3 addresses must follow RFC1812 etc.
Layer 2 switch != Router. They commonly do Ethernet stuff.

That
is what's the differents between a switch and a router for the view of
theoritical.
As to the 3 Layer switch and router, both of them work as a distributor
based on the IP address. Just some small differents usage and
implemention.
Of coourse, we disscuss this problem on the switch and router on the same
layer.
A router decrements the IP TTL field.
It should also not propagate broadcast IP packets (subnet or all 1's).
(Any other hard requirements?)
