Understanding Bridging and VLANs on EX Series Switches
Network switches use Layer 2 bridging protocols to discover the topology of their LAN
and to forward traffic toward destinations on the LAN.
This topic explains the following concepts regarding bridging and VLANs on Juniper
Networks EX Series Ethernet Switches:
