Configuring a VRF instance
About this task
Configure a VRF instance to provide a virtual routing interface for a user.
Procedure
1. In the navigation tree, open the following folders: Configuration > IP.
2. Click VRF.
3. Click Insert.
4. Specify the VRF ID.
5. Name the VRF instance.
6. To enable the VRF to send VRF Lite-related traps, select TrapEnable.
7. Configure the other parameters as required.
8. Click Insert.
VRF field descriptions
Use the data in the following table to help you use the VRF tab.
Name Dexcription
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 module management.
TrapEnable Enables the VRF to send VRF Lite-related traps (VrfUp and VrfDown).
MaxRoutes Configures the maximum number of routes allowed for the VRF. The default value is 10000, except for the
GlobalRouter, which is 250000.
RpTrigger Specifies the Routing Protocol (RP) triggers for the VRF.
The triggers are used to initiate or shutdown routing protocols on a VRF. The protocols include RIP, OSPF and BGP.
Multiple RPs can be acted upon simultaneously. Also, you can use this option to bring individual RPs up in steps.
MaxRoutesTrapEnable Enables the generation of the VRF Max Routes Exceeded traps.
Configuring interVRF route redistribution policies
Before you begin
• VRF instances exist.
• Configure route policies, if required.
• Change the VRF instance as required.
About this task
Configure interVRF route redistribution so that a VRF interface can announce routes that other protocols learn, for example, OSPF or BGP. Use a route policy to control the redistribution of routes.
Procedure
1. In the navigation tree, open the following folders: Configuration > IP.
2. Click Policy.
3. Click the Route Redistribution tab.
4. Click Insert.
5. Choose the source and destination VRF IDs.
6. Choose the protocol and route source.
7. Select Enable.
8. Choose the route policy to apply to the redistributed routes.
9. Configure other parameters as required.
10. Click Insert.
11. Click the Applying Policy tab.
12. Select RedistributeApply, and then click Apply.

Use the data in the following table to use the Route Redistribution tab.
Name Description
DstVrfId Specifies the destination VRF ID to use in the redistribution.
Protocol Specifies the protocols for which you want to receive external routing information.
SrcVrfId Specifies the source VRF ID to use in the redistribution.
RouteSource Indicates if the protocol receives notification about the routes this source learns. The route source is equivalent to the owner in the routing table.
Enable Enables or disables route redistribution.
RoutePolicy Specifies the route policies to apply to the redistributed routes from the source VRF. Use the route policy to determine whether the system advertises a specific route to the specified protocol.
Metric Specifies the metric announced in advertisements.
MetricType Specifies the metric type (applies to OSPF and BGP only).
Specifies a type 1 or a type 2 metric. For metric type 1, the cost of the external routes is equal to the sum of all internal

Name Description
costs and the external cost. For metric type 2, the cost of the external routes is equal to the external cost alone.
Subnets Indicates that subnets must be advertised individually (applies to OSPF only).

2. Click VRF.
3. Click the VRF-Ports tab.
4. To change the VRF, double-click the BrouterVrfId field for the port.
You can associate a port with more than one VRF.
5. Choose the required VRFs and click Ok.
6. Click Apply.

VrfCount Shows the number of VRF instances associated with this port.
BrouterVrfId Shows the VRF ID for this brouter port.
Name Description BrouterVrfName Shows the VRF name for this brouter port.
Viewing global VRF status information
About this task
View global VRF status information to determine the number of VRFs that are configured and active.
Procedure
1. In the navigation tree, open the following folders: Configuration > IP.
2. Click VRF.
3. Click the Global Status tab.
Global Status field descriptions

Name Description
ConfigNextAvailableVrfId Specifies the number of the next available Virtual Router ID (index).
ConfiguredVRFs Specifies the number of VRFs configured on this network element.

Viewing VRF instance statistics and status information
About this task
View VRF instance status information to determine the operational status of each VRF, as well as other operational parameters.

Selecting and launching a VRF context view
About this task
Use this procedure to switch to another VRF context view when you use the embedded EDM.
GlobalRouter is the default view at log in. You can configure both Global Router (GRT) and Virtual Routing and Forwarding (VRF) instances when you launch a VRF context view. You can open only five tabs for each EDM session.
Important:
If you log out from the GRT view, the system generates a warning: all tabs will be closed – and your session terminates. If you close a VRF view tab, you close only that view.
Note:
The Set VRF Context view function is not available to users in a service provider deployment where only a tenant VRF view is assigned. If you use a tenant VRF view, we recommend that you use the applicable EDM plugin with COM to access EDM. COM provides VRF mapping and Role-Based Access Control.
