■ From Global Configuration mode, use this command to create a virtual router
or access the context of a previously created virtual router or a VRF.
■ From Domain Map Configuration mode, use this command to map the VR to a
user domain name. Use the no version in this mode to delete the VR parameter
and assign the default VR.
■ A VR name consists of 1–32 alphanumeric characters.
■ After you are in the context of a particular VR or VRF (indicated by the change
in the prompt), all subsequent commands you enter apply to that context until
you exit the context.
■ Use the no version of the command only to delete the VR and return the router
to the default VR. Issuing the command no virtual-router vrName.vrfName has
no effect.
■ Issuing a no version of this command (no virtual-router : vrfName or
no virtual-router vrName : vrfName) that specifies an existing VRF displays only
the error message: “ Cannot delete a VRF with this command.” You must use
the no ip vrf command to remove a VRF.
NOTE: See the JUNOSe Command Reference Guide for additional information.
■ Use the wait-for-completion keyword with the no version if you require a
synchronous deletion of a VR, such as when executing Telnet or console
commands through an external script. Alternatively, you might want to use this
keyword if the VR being deleted has many configured VRFs and someone might
attempt to re-create the VR before all the VRFs have been deleted. If you do not
issue the wait-for-completion keyword in those circumstances, a virtual-router
command issued as soon as the prompt appears could fail because the router is
still deleting VRFs. You can specify a period during which the CLI waits before
it returns a prompt. If you do not specify a wait time, then the CLI does not
return a prompt until the operation is complete. You can press Ctrl+c to break
out of the wait period early.
■ See virtual-router.
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
