Configure a VRF Instance

About this task

Configure a VRF instance to provide a virtual routing interface for a user.

Note

Note

The maximum routes of IPv4 and IPv6 for Global Router (GRT) are non-configurable and fixed at the system limits.

Maximum route traps are not generated on GRT. For non-default VRFs, the permitted maximum routes can be lower than system limits and traps generate when the limit is exceeded.

Procedure

  1. In the navigation pane, expand Configuration > VRF.
  2. Select VRF.
  3. Select the VRF tab.
  4. Select Insert.
  5. Specify the VRF ID.
  6. Type a name for the VRF instance.
  7. Configure VRF Lite-related traps.
  8. Configure the optional parameters as required.
  9. Select Insert.

VRF Field Descriptions

Use the data in the following table to help you use the VRF tab.

Name

Description

Id

Specifies the ID number of the VRF instance. VRF ID 0 is reserved for the GlobalRouter.

Name

Names the VRF instance.

ContextName

Identifies the VRF. The SNMPv2 Community String or SNMPv3 contextName denotes the VRF context and is used to logically separate the MIB port management.

TrapEnable

Enables the VRF to send VRF Lite-related traps (VrfUp and VrfDown). The default is enabled.

MaxRoutes

Configures the maximum number of routes allowed for the VRF, which varies depending on the hardware. For scaling information, see VOSS Release Notes.

The default value varies for the GlobalRouter and non-default VRFs, depending on your hardware platform.

RpTrigger

Specifies the Routing Protocol (RP) triggers for the VRF. The triggers are used to initiate or shutdown routing protocols on a VRF. You can act upon multiple RPs simultaneously. You can also use this option to bring individual RPs up in steps.

MaxRoutesTrapEnable

Enables the generation of the VRF Max Routes Exceeded traps. The default is enabled.

Ipv6MaxRoutes

Configures the maximum number of IPv6 routes allowed for the VRF, which varies depending on the hardware. For scaling information, see VOSS Release Notes.

The default value varies for the GlobalRouter and non-default VRFs, depending on your hardware platform.

Ipv6MaxRoutesTrapEnable

Enables SNMP trap generation after the maximum number of IPv6 routes are reached.

The default is enabled.

Active

Displays if the VRF is active (true).

Origin

Displays the VRF origin.

CONFIG indicates the VRF was created manually. DYNAMIC indicates the VRF was created dynamically.

The Default VRF and the MGMT VRF are considered DYNAMIC.

Note: Only manually configured VRFs are visible in running-config.
