Configure DvR-VRRP Coexistence
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
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. |
