OS for EX Series Ethernet Switches, Release 10.4
This configuration example creates two IP subnets, one for the sales VLAN and the
second for the support VLAN. The switch bridges traffic within a VLAN. For traffic passing
between two VLANs, the switch routes the traffic using a Layer 3 routing interface on
which you have configured the address of the IP subnet.
To keep the example simple, the configuration steps show only a few devices in each of
the VLANs. Use the same configuration procedure to add more LAN devices.
Configure Layer 2 switching for two VLANs:
To quickly configure Layer 2 switching for the two VLANs (
quickly configure Layer 3 routing of traffic between the two VLANs, copy the following
commands and paste them into the switch terminal window:
