Configure a DvR Controller or a DvR Leaf Globally

About this task

Configure a node to perform the role of either a Controller or a Leaf, within the DvR domain.

Before you begin

Important

For DvR Leaf Configuration only:

You must enable the dvr-leaf-mode boot flag before you configure a node as a DvR Leaf node. Navigate to Configuration > Edit > Chassis. On the Boot Config tab, select EnableDvrLeafMode.

Ensure that you save the current configuration on the switch, before you enable the flag. Enabling the flag removes all non-DvR configuration on the switch.

Procedure

In the navigation pane, expand Configuration > Fabric.
Select DVR.
Select the Globals tab.
In the DomainId field, type the domain ID.

Note

A Controller or a Leaf node can belong to only one DvR domain.
In the Role field, select the role of the node.
Optional: On a Controller node, disable injection of default routes into the DvR domain. Select InjectDefaultRouteDisable.

Note

This field applies only to Controllers. Attempting to select this field on a Leaf node displays an error message.
Update the fields as necessary, and then select Apply to save your configuration.

Globals Field Descriptions

Use the data in the following table to use the Globals tab.


Field	Descriptions
DomainId	Identifies the domain that the node belongs to. The range for a Controller or a Leaf is 1 to 255. Set to 0 if is not configured.
Role	Specifies the role of the node in the domain as one of the following: controller leaf isolatedController
Enable	Specifies whether Distributed Virtual Routing (DvR) is enabled on the node. Configuring a Controller or Leaf sets this parameter to true.
DomainIsid	Uniquely identifies the domain I-SID that the node belongs to. 0 indicates that is not configured.
BackboneIsid	Uniquely identifies the backbone I-SID that the node belongs to. The valid backbone I-SID is 16678216; it is configured to 0 if is not configured.
GatewayMac	Specifies the Gateway MAC address used by all domains.
InbandMgmtIp	Specifies the In-band Management IP address configured under IS-IS. You can use this IP address to manage the node, irrespective of whether DvR is enabled on it.
InjectDefaultRouteDisable	Specifies whether injection of default routes is disabled on the Controller in the domain. By default, Controllers inject default routes into the domain so that all Leaf nodes in the domain learn these routes with the next hop as the Controller that advertised it. Selecting this field disables this behavior.
VirtualIstLocalAddr	Specifies the local IP address of vIST, if vIST is configured on a Leaf. You cannot configure vIST cannot on a Controller.
VirtualIstLocalMask	Specifies the local subnet mask of vIST, if vIST is configured on a Leaf. You cannot configure vIST on a Controller.
VirtualIstPeerAddr	Specifies the peer IP address of vIST, if vIST is configured on a Leaf. You cannot configure vIST on a Controller.
VirtualIstClusterId	Specifies the cluster ID of vIST, if vIST is configured on a Leaf. You cannot configure vIST on a Controller. Set to 0 if vIST is not configured.
VirtuaIIstIsid	Specifies the I-SID if vIST is configured.
OperState	Specifies the operational state of the node.
VrrpEnable Note: Exception: not supported on 5320 Series or 5420 Series.	Enables Virtual Router Redundancy Protocol (VRRP) advertisements on DvR VLAN Service Instance Identifiers (I-SIDs). The default value is disabled.
VrrpPriority Note: Exception: not supported on 5320 Series or 5420 Series.	Configures the VRRP priority for the elected VLAN and associated I-SID. Switches advertise their priority to use in the primary router election process. When multiple Controllers elect the same DvR VLAN and I-SID, the Controller with the higher priority becomes the primary router. The elected Controller sends VRRP advertisements on all DvR VLANs. The default value is 100.
VrrpElectionVlanId Note: Exception: not supported on 5320 Series or 5420 Series.	Displays the election VLAN for VRRP on DvR I-SIDs. A value of 4095 indicates no elected VLAN exists.
