Understanding Integrated Routing and Bridging (IRB) Interfaces in a Junos Fusion Enterprise

date_range 13-Jan-21

In most campus networking environments, endpoint devices must have a path to send and receive Layer 3 traffic.

In a typical Junos Fusion Enterprise deployment, the EX9200 switch assumes the responsibilities of an aggregation layer switch and is typically the gateway to layer 3. Integrated routing and bridging (IRB) interfaces are, therefore, configured on the EX9200 switches acting as aggregation devices to move traffic between Layer 2 and Layer 3.

See Understanding Integrated Routing and Bridging for information on configuring IRB interfaces.

See the Adding Layer 3 Support to a Junos Fusion Enterprise section of the Enabling Junos Fusion Enterprise on an Enterprise Campus Network for a sample IRB interface configuration in a Junos Fusion Enterprise.
