Configure 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 pane, expand .
- Select VRF.
- Select the VRF tab.
- Select Insert.
- Specify the VRF ID.
- Type a name for the VRF instance.
- Configure VRF Lite-related traps.
- Configure the optional parameters as required.
- 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 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. 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.
|
Sd-Wan Local
Breakout Note: Not supported on switch models that
support only a single active VRF with IP
configuration.
|
Enables Local Breakout on the VRF. The default is false (disabled). |
