Explanation

Implement Virtual Switching Extension (VSX) on pairs of ERPS switches at the same site. Then combine multiple links between two data centers into VSX LAGs (MC-LAGs) is not part of a valid strategy for load sharing traffic across the links in an Ethernet Ring Protection Switching (ERPS) ring. ERPS is a feature that provides loop prevention and fast convergence for Layer 2 networks that use ring topologies. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. VSX LAGs or MC-LAGs are LAGs that span across two VSX nodes and provide load balancing and resiliency. However, VSX LAGs or MC-LAGs are not supported by ERPS because they can create loops in the ring topology. A better way to load share traffic across the links in an ERPS ring would be to use link aggregation groups (LAGs) between two nodes in a ring as long as they are not multi-chassis LAGs (MC-LAGs).
