This document provides guidance on deploying and verifying AOS-CX switches with L3 Virtual Router Redundancy Protocol (VRRP) gateways across an Ethernet Ring Protection Switching (ERPS) ring that provides Data Center Interconnect (DCI) functionality.
The combination of LACP, L2 ERPS and L3 VRRP provides both L2/L3 loop free network connectivity across multiple DCs.
Virtual Switching Extension (VSX) combined with ERPS within each Data Center (DC) provides dual control plane link aggregation groups (LAGs) to achieve maximum network high availability.
