ADTRAN AOS Version R10.1.0 Command Reference Manual page 2085

Command Reference Guide
vrf forwarding <name>
Use the vrf forwarding command to assign an interface to a specific VPN routing and forwarding (VRF)
instance. Use the no form of this command to remove the interface from the named VRF instance and
assign it to the unnamed default VRF.
Keep in mind that changing an interface's VRF association will clear all IP-related
settings on that interface.
Syntax Description
<name>
Default Values
By default, interfaces are associated with the default VRF that is unnumbered.
Command History
Release 16.1
Release 17.8
Functional Notes
VRF instances must be created first before an interface can be assigned. An interface can only be
assigned to one VRF, but multiple interfaces can be assigned to the same VRF.
An interface will only forward IP traffic that matches its associated VRF.
VRF on AOS products allows a single physical router to be partitioned into multiple virtual routers. Each
router instance has its own route table and interface assignments. Beginning with Release 16.1, all AOS
routers supporting multiple VRF instances (multi-VRF) have an unnamed default VRF instance regardless
of whether multi-VRF is configured.
Usage Examples
The following example assigns the bvi 1 interface to the VRF instance named RED:
(config)#interface bvi 1
(config-bvi 1)#vrf forwarding RED
60000CRG0-35E
Specifies the name of the VRF to which to assign the interface.
Command was introduced.
The keyword ip was removed from this command.
