Compare and contrast Layer 2 addresses with Layer 3 addresses
What will be an ideal response?
Layer 2 addresses are used only for local delivery when transporting a frame across a shared
local medium. When a packet crosses an internetwork, it gets encapsulated in a new data link
layer header with new Layer 2 addresses for each hop it takes. Layer 2 addresses use a flat
addressing scheme and do not indicate on what network a device is located. If a device is moved
to another network, its Layer 2 address does not need to change. Layer 3 addresses, on the other
hand, are carried from source to destination host across an internetwork. Layer 3 addresses use a
hierarchical addressing scheme and indicate a network number and host identifier.
