Configuring Multiple VRF

Configuring VRF Instances

Configuring the Multiple VRF feature consists of the following:
•
Creating a VRF instance with a low profile or the default max profile.
•
Assigning one or more IP interfaces to the instance.
•
Configuring routing protocols to operate within a specific instance.
The initial configuration of an OmniSwitch consists of a default VRF instance, which is always active
when the switch starts up and is not removable from the switch configuration. Any subsequent
configuration of switch applications applies only to the default instance. To provide multiple, independent
IP routing domains on the same switch, configuring additional VRF instances is required.
The VRF CLI is context-based in that commands used to configure VRF-aware applications are applied to
the active VRF instance. A VRF instance becomes active when the instance is either created or selected
using the vrf command.
A VRF instance is identified by a name, which is specified at the time the instance is configured. For
example, the following command creates the IpOne instance:
-> vrf create IpOne
IpOne: ->
In this example, instance IpOne is created and made the active VRF context at the same time. The CLI
command prompt indicates the active context by displaying the name of the VRF instance as part of the
actual prompt. Any subsequent commands entered on this command line are applied to the IpOne
instance.
Note. Configuring a VRF instance name is case sensitive. As a result, it is possible to accidentally create or
delete instances. Use the
adding, or removing instances.
Within the context of the default VRF instance, it is also possible to enter configuration commands for
another instance. For example, to configure an IP interface for instance IpOne from within the CLI context
of the default instance, prefix the ip interface command with vrf command followed by the name of the
instance. For example:
-> vrf IpOne ip interface intf100 address 100.1.1.1/24 vlan 100
->
The above command creates the IP interface for VRF IpOne but does not change the CLI context in which
the command was entered. The default VRF instance remains the active context.
Note. The default VRF instance is the only VRF CLI context within which configuration of another
instance is allowed.
Configuring the VRF Profile
By default, the max profile capabilities are applied when a VRF instance is created. A max profile VRF
supports dynamic routing protocols and other supported VRF limits. To create a VRF instance with low
profile capabilities, use the
-> vrf create IpTwo profile low
IpTwo-low::->
