Glossary

NOTE: In a VLT environment, VRRP configuration acts as active-active and if route is not present in any of the VRRP
nodes, the packet to the destination is dropped on that VRRP node.

VRRP Configuration
By default, VRRP is not configured.
Configuration Task List
The following list specifies the configuration tasks for VRRP.
● Creating a Virtual Router (mandatory)
● Configuring the VRRP Version for an IPv4 Group (optional)
● Assign Virtual IP Addresses mandatory)
● Setting VRRP Group (Virtual Router) Priority (optional)
● Configuring VRRP Authentication (optional)
● Disabling Preempt (optional)
● Changing the Advertisement Interval (optional)
● Track an Interface or Object
● Setting VRRP Initialization Delay
For a complete listing of all commands related to VRRP, refer to Dell EMC Networking OS Command Line Reference Guide.
Creating a Virtual Router
To enable VRRP, create a virtual router. In Dell EMC Networking Operating System (OS), the virtual router identifier (VRID)
identifies a VRRP group.
To enable or delete a virtual router, use the following commands.
● Create a virtual router for that interface with a VRID.
INTERFACE mode
vrrp-group vrid
The VRID range is from 1 to 255.
NOTE: The interface must already have a primary IP address defined and be enabled, as shown in the second example.
● Delete a VRRP group.
INTERFACE mode
no vrrp-group vrid
1100
