is posible this configuration VRRP/VLT on 2 sites ?
Dear community,
I hope this message finds you well. I am writing to inquire about the feasibility of implementing the following: I need to configure two sites with high availability at layer 2, which will be connected through two optical fibers using the LACP protocol, allowing all VLANs between the sites.
Site A has two Dell core devices, Dell S4148F (OS10), which will be configured in a VLT domain and VRRP for the VLAN gateway. Site B has two Dell S4048-ON devices (OS9), which will also be configured in VLT and VRRP.
The idea is to configure VRRP in both sites and establish communication between them for the virtual IP address of the VLANs. Is it possible to implement this configuration in Dell, where each site, with its VLT pair for high availability, shares the VRRP for the virtual IP address?
Thank you for your attention, and any guidance you can provide will be greatly appreciated.
Best regards,
DELL-Erman O

Hello, it is possible to implement VRRP in both sites. However, VRRP and VLT are two independent protocols and run separately. Please take a look at the below articles, I believe they can help. And our community may contribute with configuration.

Yes, what is sought is for VRRP to create a virtual IP between both sites, which will serve as the designated gateway IP for the VLANs. VLT will be set up for the Site A pair, and another VLT domain for the Site B pair (independent between sites). Then, VRRP will be set up on the 4 devices (A1, A2, B1, and B2), and the VIP GW will be located among them. These sites are connected at Layer 2 through fiber optics directly connected to the A1, A2, B1, and B2 devices. So, is this configuration valid on these Dell devices and is it a good practice, or are there other alternatives for this solution?
best regards
