Selecting A Vrf Instance - Alcatel-Lucent OmniSwitch 9900 Series Network Configuration Manual

Configuring Multiple VRF
Changing the profile for an existing VRF instance is not allowed. To change the profile, first delete the
VRF then create it again with a different profile. For example, to change profile IpTwo to a max profile
VRF, use the following commands:
-> no vrf IpTwo
-> vrf create IpTwo profile max
IpTwo-low::->
In this example, the profile max parameter option is not needed, since the max profile is applied by
default. However, this parameter was used here to demonstrate the command syntax.
The total number of VRFs allowed depends on the available switch memory. At 80% memory usage, a
low memory warning is displayed when a new VRF is created. When 90% usage is reached, creating a
new VRF is stopped. For example:
-> vrf create LowProfVrf400 profile low
+++ WARNING: Memory usage over 80%, creating VRF
->vrf create LowProfVrf412 profile low
ERROR: resource allocation failure
+++ ERROR: Memory usage over 90%, VRF creation failed
Use the show vrf-profiles

Selecting a VRF Instance

Moving between VRF instances is done by selecting an existing instance to become the active VRF CLI
context. The vrf command is also used to select an existing instance. For example, the following
command selects the IpTwo instance:
IpOne: -> vrf IpTwo
IpTwo: ->
In the above example, selecting the IpTwo instance changed the VRF CLI context from IpOne to IpTwo.
Any subsequent commands entered apply to the IpTwo instance.
If the instance name specified with the vrf command does not exist, an error message is displayed. For
example:
-> vrf IpFour
ERROR: VRF IpFour does not exist.
To return to the default VRF instance from within the context of another instance, enter the vrf command
with or without the optional default parameter. For example, both of the following commands return the
CLI context to the default VRF instance:
IpOne: -> vrf
IpOne: -> vrf default
Note that the command prompt for the default VRF instance does not display the instance name.
