Integrated Routing 21 NOTE In configurations with two backbones connected to the same edge fabric, routing is not supported between edge fabrics that are not directly attached to the same backbone. Routing over multiple backbones is a multi-hop topology and is not allowed. Integrated Routing Integrated Routing is a licensed feature that allows 8-Gbps FC ports to be configured as EX_Ports (or VEX_Ports) supporting Fibre Channel routing. This license eliminates the need to add an FR4-18i blade to the Brocade DCX and DCX-4S, or to use the Brocade 7500 for FC-FC routing purposes. Using 8-Gbps ports for Fibre Channel routing provides double the bandwidth for each FCR connection (when connected to another 8-Gbps-capable port). You need an Integrated Routing license for the following: • Brocade DCX and DCX-4S (FC8-16, FC8-32, FC8-48, FC8-64, FS8-18, and FX8-24 blades) • Brocade 5100 switch • Brocade 5300 switch • Brocade VA-40FC switch • Brocade 7800 Extension Switch • Brocade Encryption Switch You do not need a license for EX_Ports on the Brocade 7500 Extension Switch or FR4-18i blade. Enabling the Integrated Routing license and capability does not require a switch reboot. For the Brocade DCX and DCX-4S, if you do not have an Integrated Routing license, you cannot use EX_Ports on the 8-Gbps port blades; you can, however, use EX_Ports on the FR4-18i blade without a license. NOTE You cannot use EX_Ports on the FR4-18i blade and Integrated Routing in the same chassis. Integrated Routing is not supported on 8-Gbps blades in the Brocade 48000. Fibre Channel routing concepts Fibre Channel routing introduces the following concepts: • Fibre Channel router (FC router) A switch running the FC-FC routing service. See "Supported platforms for Fibre Channel routing" on page 456 for a list of platforms that can be FC routers. • EX_Port, VEX_Port An EX_Port and VEX_Port function similarly to an E_Port and VE_Port respectively, but terminate at the switch and do not propagate fabric services or routing topology information from one edge fabric to another. See the Fibre Channel over IP Administrator's Guide for details about VE_Ports. Fabric OS Administrator's Guide 457 53-1001763-01
