1. connect 2 existing LANs (CS, math)
-- different organizations want to be connected
2. LAN too big; need to split it, but stay connected
-- too many stations or traffic for one LAN
3. connect geographically separate LANs.
-- eg, 2 offices in different towns need connecting ( Remote Bridges, with PPP connection between bridges)
4. reduce collisions
-- help increase efficiency
--help restrict traffic to one LAN
