Configure a DvR Controller or a DvR Leaf Globally

Before you begin

Important

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.

About this task

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

Procedure

  1. In the navigation pane, expand Configuration > Fabric.
  2. Select DVR.
  3. Select the Globals tab.
  4. In DomainId, type the domain ID.
    Note

    Note

    A Controller or a Leaf node can belong to only one DvR domain.

  5. In Role, select the role of the node.
  6. Optional: On a Controller node, disable injection of default routes into the DvR domain. Select InjectDefaultRouteDisable.
    Note

    Note

    This parameter applies only to Controllers. Attempting to select this field on a Leaf node displays an error message.

  7. Update the parameters as necessary, and then select Apply.

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. Select this parameter to disable 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

Enables Virtual Router Redundancy Protocol (VRRP) advertisements on DvR VLAN Service Instance Identifiers (I-SIDs). The default value is disabled.

VrrpPriority

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

Displays the election VLAN for VRRP on DvR I-SIDs. A value of 4095 indicates no elected VLAN exists.
