Juniper layer 3 switch configuration.

In this example a single mx series device is configured to act as a basic single vlan switch. Three connections are in place. A layer 2 virtual switch which isolates a lan segment with its spanning tree protocol instance and separates its vlan id space filters and forwards traffic only at the data link layer. I want to create 5 vlans on my layer 3 switch vlan 10 20 30 40 50 with 1 separate vlan on each unmanaged switch vlan 30 on one unmanaged and vlan 40 on the other.

The customer s customer edge ce switch uses a routing protocol such as bgp or ospf to communicate with the service provider s provider edge pe switch to carry ip prefixes across the network. Switch config interface vlan2 switch config if ip address 10 1 2 1 255 255 255 0 switch config if no shutdown.

Learn how ex series ethernet switches provide performance flexibility and ease of management. To enable inter vlan communication you configure a layer 3 routing logical interface on the switch for each vlan. To configure vlan with l3 routing follow the next steps. I have a cisco sf300 layer 3 switch 2 unmanaged switches and a utm.

Juniper ex series switches support many of the standard junos os routing protocols including static routing rip ospf is is and bgp as well as features such as vrrp. Layer 3 routing is not performed.
