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

Example

host1#show aaa domain-map
Domain: boston; virtual-router: default

Tunnel Tunnel Tunnel Tunnel Tunnel  Tunnel   Tunnel  Tunnel
 Tag    Peer  Source  Type  Medium Password   Id    Hostname
------ ------ ------ ------ ------ --------  ------ --------
31     <null> <null> l2tp   ipv4   <null>    <null> <null>

         Tunnel
Tunnel   Server     Tunnel
 Tag      Name    Preference
------   ------   ----------
31       <null>   2000

See show aaa domain-map.

show configuration

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 Command-Line Interface, for details.

Example

host1#show configuration virtual-router default
virtual-router default
ip domain-lookup
ip name-server 10.2.0.3
ip domain-name "junipercom.com"
!
host f 10.10.0.129 ftp anonymous null
interface null 0

interface fastEthernet 0/0
 ip address 192.168.1.155 255.255.255.0

See show configuration.

show ip forwarding-table slot

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

Example

host1#show ip forwarding-table slot 9
Free Memory = 14,328KB
  Virtual Router      Memory       Load Errors     Status
                      (KB)
----------------     ---------    -------------    --------
   vr1                 4128              0          Valid
   vr2                 3136              0          Valid
   vr3                 2256              0          Valid
   vr4                 1512              0          Valid
 default               1024              0          Valid
-----------------------------------------------------------

See show ip forwarding-table slot.

show virtual-router

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 Command-Line Interface, for details.
