Spanning Tree in an ERS8600 Routed Network

In the example above, a brouter port was used to connect to the network core. A brouter port is a single-
port VLAN that can route IP packets as well as bridge all non-routable traffic. The difference between a
brouter port and a standard IP protocol-based VLAN configured to do routing is that the routing interface
of the brouter port is not subject to the Spanning Tree state of the port. Hence, using brouter ports
eliminates the Spanning Tree protocol from the backbone network.
If VLAN connectivity is required in the core to support non-IP protocols, care must be taken to prevent
blocked ports due to Spanning Tree. This could occur if using one Spanning Tree (STG) instance.
