24 VLAN Routing Deleting an MSTP instance 1. Select MSTP from the Spanning Tree list. The VLAN - STP Configuration dialog box displays the Available MSTP Instances list. 2. Select an MSTP instance from the Available MSTP Instances list, or enter the MSTP instance number. 3. Click the Delete button. 4. Click the right arrow button to move the MSTP instance to the Selected VLAN list. 5. Click OK. VLAN Routing VLAN restricts the broadcast domain to only its interface members. If nodes connected to two different VLANs want to communicate, they require an external router to route between the VLANs. Optionally, Brocade DCB products offer the ability to create Switch Virtual Interface (SVI) to route between VLANs. An SVI is a VLAN of switch ports represented by one interface to a routing or bridging system. There is no physical interface for the VLAN and the SVI provides the Layer 3 processing for packets from all switch ports associated with the VLAN. There is one-to-one mapping between a VLAN and SVI; therefore, only a single SVI can be mapped to a VLAN. The VLAN is mapped to a network address using the SVI. All the nodes in the VLAN will belong to the subnet of the SVI. NOTE In IOS terms, an SVI is also called a Virtual Routing Interface (VRI). The SVI in DCB products and VRI in IOS products mean the same. Managing IP addresses on a switch virtual interface Switch virtual interfaces (SVIs) can be added to port VLANs when you create or modify VLAN definitions. SVIs can only be created in Layer 3 products. Once VLAN definitions are deployed to products, you can add an IP address to the SVI by completing the following steps. 1. On the VLAN Manager dialog box, complete one of the following tasks: • Click the VLAN View tab and expand the VLAN node. Select the product that contains the switch virtual interface that you want to define. The list of interfaces appears in the interface list. Click the SVI in the list of interfaces to select it. • On the Product View tab, expand the product or group folders. Expand the products under the folder and select the VLAN that contains a switch virtual interface. The list of interfaces appears in the interface list. Click the SVI in the list of interfaces to select it. NOTE For DCB products, you must select the port VLAN itself to enable the IP button. 2. Click the IP button on the tool bar.
