ADTRAN AOS Version R10.1.0 Command Reference Manual page 3066

Command Reference Guide
vrf <name>
Use the vrf command to associate a Dynamic Host Configuration Protocol version 4 (DHCPv4) address
pool with a specific VPN routing and forwarding (VRF) instance. An address pool can only be assigned to
one VRF instance, but a VRF instance can have multiple address pools providing addresses for it. Use the
no form of this command to remove the association with the named VRF instance and assign the address
pool to the default (unnamed) VRF instance.
Keep in mind that associating a DHCPv4 address pool with a nondefault VRF instance
will clear all previously configured settings for the address pool.
Syntax Description
<name>
Default Values
By default, DHCPv4 address pools are associated with the default unnamed VRF instance.
Command History
Release 17.1
Functional Notes
VRF instances must be created first before a DHCPv4 address pool can be assigned. An address pool can
only be assigned to one VRF instance, but multiple address pools can be assigned to the same VRF
instance.
VRF instances 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. Therefore, executing the abovementioned
commands without specifying a VRF instance will only affect the default unnamed VRF instance.
Usage Examples
The following example creates a DHCPv4 address pool named PRIVATE and assigns it to the VRF
instance named RED:
(config)#ip dhcp pool PRIVATE
(config-dhcp)#vrf RED
WARNING!!! All settings for this pool have been removed
(config-dhcp)#network 10.22.199.0 255.255.255.0
60000CRG0-35E
Specifies the name of the VRF instance to associate with the DHCPv4
address pool.
