MC-LAG and STP Configuration on Enterprise SONiC Switch

Written by liuzijia on . Posted in Implementation.

MC-LAG and STP Configuration on Enterprise SONiC Switch 1. Background 2. Topology Requirements 3. Configuration Steps 4. Verification 1. Background MC-LAG inherently provides loop avoidance mechanisms. In normal operation, MC-LAG-based networks do not generate Layer 2 loops. However, in multi-tier MC-LAG deployments, loops may still occur due to incorrect network design, incomplete initial configuration, or device reboot with empty configuration. In such cases, STP can be deployed as a safeguard to prevent loop formation. 2. Topology Requirements Switches adopt cross-device...
