Usage Guideline DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide This command is used to create a new VRF instance and enter VRF configuration mode. After a new VRF instance is created, a new VRF routing table will be created. With the no form of this command, one VRF will be deleted. The related VRF routing table will be deleted at the same time. And all routing instances based on this VRF will be destroyed too. All IP interfaces associated to this VRF will be restored to global routing instance. In the other words, all configurations based on this VRF will be removed. There is a limitation about the max number of VRF instances and it is project dependent. Use the command show ip vrf and show ip route vrf to check the settings. Example This example shows how to create and delete a VRF instance. DXS-3600-32S#configure terminal DXS-3600-32S(config)# ip vrf VPN-A DXS-3600-32S(config-vrf)#exit DXS-3600-32S(config)# no ip vrf VPN-A DXS-3600-32S(config)# 72-5 ip vrf forwarding This command is used to associate one interface to a VRF instance. Use the no form of this command to restore one interface to global routing instance. ip vrf forwarding vrf-name no ip vrf forwarding vrf-name Parameters vrf-name Specifies the name of the VRF.

ip vrf forwarding
This command is used to associate one interface to a VRF instance. Use the
no
form of this command to restore one
interface to global routing instance.
ip vrf forwarding
vrf-name
no ip vrf forwarding
vrf-name
Parameters
72-6
maximum routes
This command is used to limit the maximum routes within the VRF. Use the
no
form of this command to remove the
limit.
maximum routes
limit
{
warn-threshold
| warning-only}
Usage Guideline
This command is used to create a new VRF instance and enter VRF configuration
mode. After a new VRF instance is created, a new VRF routing table will be created.
With the
no
form of this command, one VRF will be deleted. The related VRF routing
table will be deleted at the same time. And all routing instances based on this VRF
will be destroyed too. All IP interfaces associated to this VRF will be restored to
global routing instance. In the other words, all configurations based on this VRF will
be removed. There is a limitation about the max number of VRF instances and it is
project dependent.
Use the command
show ip vrf
and
show ip route vrf
to check the settings.
Example
This example shows how to create and delete a VRF instance.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# ip vrf VPN-A
DXS-3600-32S(config-vrf)#exit
DXS-3600-32S(config)# no ip vrf VPN-A
DXS-3600-32S(config)#
vrf-name
Specifies the name of the VRF.
Default
By default, no interface is associated to a VRF instance.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 15
Usage Guideline
This command is used to associate an interface to one VRF instance. After one
interface is associated to one VRF instance with this command, its IP address will be
restored to unspecified. User needs to set its IP address before use it.
By associating interfaces to different VRF, the interfaces in different VRF can be
configured with same IP address. The IP address space in one VRF is individual and
can overlap among different VRFs.
Use the command
show ip vrf
to check the settings.
Example
This example shows how to associate VLAN 100 interface to VRF VPN-A.
DXS-3600-32S#configure terminal
DXS-3600-32S(config)# interface vlan 100
DXS-3600-32S(config-if)# ip vrf forwarding VPN-A
DXS-3600-32S(config-if)# ip address 100.1.1.1 255.255.255.0
