Displaying VRRP in a VRF Configuration
To display information on a VRRP group that is configured on an interface that belongs to a VRF instance, use the following
commands.
● Display information on a VRRP group that is configured on an interface that belongs to a VRF instance.
show running-config track [interface interface]
● Display information on VRRP groups configured on interfaces that belong to a VRF instance.
show vrrp vrf [vrf instance]
The following example shows verifying a configuration on VRRP in a VRF interface.
Dell#show running-config track interface tengigabitethernet 1/4
interface TenGigabitEthernet 1/4
ip vrf forwarding red
ip address 192.168.0.1/24
vrrp-group 4
virtual-address 192.168.0.254
no shutdown
The following example shows viewing the status of VRRP in a global VRF configuration.

Proxy Gateway with VRRP
VLT proxy gateway solves the inefficient traffic trombone problem when VLANs are extended between date centers and when
VMs are migrated between the two DCs. Starting from Dell EMC Networking OS 9.14.0.0, VRRP provides a much simpler
method to solve the traffic trombone problem.
This is achieved by configuring same VRRP group IDs to the extended L3 VLANs and VRRP stays active-active across all four
VLT nodes even though they are in two different VLT domains.
The following illustration shows a sample configuration with two data centers:
