Configuring a VRF instance

About this task

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

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

In the navigation tree, expand the following folders: Configuration > VRF.
Click VRF.
Click the VRF tab.
Click Insert.
Specify the VRF ID.
Name the VRF instance.
Configure VRF Lite-related traps.
Configure the other parameters as required.
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 Note: Exception: not supported on 5320-16P-4XE, 5320-16P-4XE-DC, 5320-24P-8XE, or 5320-24T-8XE.	Configures the maximum number of routes allowed for the VRF, which varies depending on the hardware. For scaling information, see Fabric Engine 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 Note: Exception: not supported on 5320-16P-4XE, 5320-16P-4XE-DC, 5320-24P-8XE, or 5320-24T-8XE.	Configures the maximum number of IPv6 routes allowed for the VRF, which varies depending on the hardware. For scaling information, see Fabric Engine 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). The 16- and 24-port 5320 Series models support a single active VRF with IP configuration; the VRF can be the GlobalRouter (GRT) or a non-default VRF:
Origin	Displays the VRF origin (DYNAMIC or CONFIG). CONFIG indicates the VRF was manually created by the user. DYNAMIC indicates the VRF was created configuring an mvpn-isid on a VLAN. The Default VRF and the MGMT VRF are considered DYNAMIC. Note: Only CONFIG VRFs are saved and visible in the running-config.
