Configuring 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 tree, expand the following folders: Configuration > VRF.
  2. Click VRF.
  3. Click the VRF tab.
  4. Click Insert.
  5. Specify the VRF ID.
  6. Name the VRF instance.

  9. Click 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 is 15488 or 15744, depending on your hardware platform.

The default value is 10000, except for the GlobalRouter, which is 15488 or 15744, 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 is 7744 or 7872, depending on your hardware platform.

The default value is 5000.

Ipv6MaxRoutesTrapEnable

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

The default is enabled.
