[ no ] ip vrf forwarding vrfName [ fallback global ]
Command introduced before JunosE Release 7.1.0.
Assigns a VRF to an interface or subinterface. Optionally specifies secondary routing
table lookup on the parent (global) virtual router forwarding table if a lookup on the initial
VRF forwarding table does not yield any results. The no version removes the assignment
or discontinues the secondary routing table lookup option.
NOTE: The ip vrf forwarding command changes the prompt to indicate that
the CLI is now in Interface or Subinterface Configuration mode within the
child VRF. This condition persists only for as long as you are configuring
attributes on the given interface within the VRF. Entering a top-level
command, such as interface, within this VRF context takes the CLI out of the
VRF context back to the parent VR context.
When you issue the ip vrf forwarding command from within the Interface
Configuration or Subinterface Configuration mode of the parent VR, the IP
address and other attributes of the interface are deleted from the interface.
You must then reconfigure the IP attributes in the context of the VRF after
issuing the command.
vrfName—Name of the VRF; a string of 1–32 alphanumeric characters
fallback global—Specifies secondary routing table lookup on the parent (global) virtual
router forwarding table, if an initial VRF forwarding table lookup does not yield results.
