Displaying VRRP in a VRF Conguration
To display information on a VRRP group that is congured on an interface that belongs to a VRF instance, use the following commands.
• Display information on a VRRP group that is congured on an interface that belongs to a VRF instance.
show running-config track [interface interface]
• Display information on VRRP groups congured on interfaces that belong to a VRF instance.
show vrrp vrf [vrf instance]
Example of Verifying and Viewing Conguration on VRRP in a VRF
The following example shows verifying a conguration 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 conguration.
Dell#show vrrp vrf red

Proxy Gateway with VRRP
VLT proxy gateway solves the inecient trac 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 trac
trombone problem.
This is achieved by conguring 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 dierent VLT domains.
The following illustration shows a sample conguration with two data centers:
