This topic describes the prerequisites to configure Integrated Routing and Bridging (IRB), including user group and task ID requirements, line card selection, Layer 3 information for the Bridge-Group Virtual Interface (BVI), MAC address planning, and routing advertisement.
User group and task ID requirements
You must be in a user group associated with a task group that includes the proper task IDs. The command reference guides include the task IDs required for each command. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Prerequisites to complete before configuring IRB
Before configuring IRB, be sure that these tasks and conditions are met:
-
Confirm that you are configuring the required line cards where you plan to support IRB in support of both Layer 3 to Layer 2 traffic flows and Layer 2 to Layer 3 traffic flows
-
Know the IP addressing and other Layer 3 information to be configured on the bridge virtual interface (BVI). For more information, see the Guidelines and restrictions to configure IRB.
-
Complete MAC address planning if you decide to override the common global MAC address for all BVIs.
-
Be sure that the BVI network address is being advertised by running static or dynamic routing on the BVI interface.
