The following table defines parameters for the dvr controller vrrp-on-dvr-isids priority command.

Configure DvR-VRRP Coexistence

Note

Note

This procedure does not apply to VSP 4450 Series, VSP 8600 Series, or XA1400 Series.

When a Layer 2 Virtual Service Network (VSN) extends outside of the DvR domain, DvR Controllers can route traffic that enters on the network-to-network interface (NNI) by using Virtual Router Redundancy Protocol (VRRP).

Before you begin

The VLAN must be a DvR VLAN. A DvR VLAN is a VLAN configured on a DvR Controller with a VLAN IP address, a VLAN I-SID, the DvR gateway IP address, and DvR enabled.

About this task

If you enable this functionality, the switch automatically creates a VRRPv2 interface with the virtual router ID (VRID) 37 and a holddown-timer configuration of 60 on the DvR VLAN that you identify for VRRP election. You can configure one VLAN for election.

Procedure

  1. Enter VLAN Interface Configuration mode:

    enable

    configure terminal

    interface vlan <1–4059>

  2. Enable VRRP election on the DvR VLAN:

    dvr vrrp-election

  3. Exit to Global Configuration mode:

    exit

  4. Optional: Configure the DvR VRRP priority for the elected VLAN:

    dvr controller vrrp-on-dvr-isids priority <1-254>

  5. Enable VRRP advertisements on all DvR VLAN Service Instance Identifiers (I-SIDs):

    dvr controller vrrp-on-dvr-isids enable

Variable Definitions

The following table defines parameters for the dvr controller vrrp-on-dvr-isids priority command.

Variable

Value

<1-254>

Configures the Virtual Router Redundancy Protocol (VRRP) priority for the elected VLAN and associated Service Instance Identifier (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.
