Monitoring Virtual Routers
Use the show virtual-router, the show configuration virtual router, and show aaa domain-map commands to display virtual router and user-domain-to-virtual-router mapping information. Use the show ip forwarding table command to display information about memory usage by virtual routers.
show aaa domain-map
- Use to display the mapping between user domains and virtual routers.
- The following keywords have significance when used as user domains:
- none—All client requests with no user domain name are associated with the virtual router mapped to the none entry
- default—All client requests with a domain present that has no map are associated with the virtual router mapped to the default entry

- Use to display configuration information for the virtual routers configured on your router.
- You can create a configuration script from the output by saving it as a file with the .scr extension.
- You can exclude information about a particular type of interface.
- You can use the output filtering feature of the show command to include or exclude lines of output based on a text string that you specify. See Chapter 2, Command-Line Interface, for details.

- Use to display the memory used by each VR configured on a line module and free memory available on the line module.
- Field descriptions
- Free Memory—Amount of memory free on the line module, in kilobytes
- Virtual Router—Name of the virtual routers configured on the line module
- Memory (KB)—Amount of memory consumed by the VR, in kilobytes
- Load Errors—Counts errors made while loading the routing table on the line module
- Status—Indicates whether the routing table for the VR is valid

- Use to display the virtual routers and VRFs configured on your router.
- Use the summary keyword to display only the total number of virtual routers and the total number of VRF instances.
- Use the detail keyword to display the status of the routing protocols configured for each virtual router.
- Use the summary keyword with the detail keyword to display the number of VRF instances for each virtual router.
- Use the output filtering feature of the show command to include or exclude lines of output based on a text string you specify. See Chapter 2, Command-Line Interface, for details.
