Describes link aggregation using LACP, explaining how to enhance bandwidth and redundancy for Layer 2 VPNs through aggregation protocols and best practices.
Key compatibility requirements enforced by LACP:
-
All aggregated links terminate on the same two systems.
-
Both systems recognize the links as belonging to the same bundle.
-
All links are configured with appropriate settings on both peers.
LACP operates by transmitting frames that contain information about the local port state and the local view of the partner system’s state. These frames are analyzed to ensure both partners are in agreement regarding bundle membership and link status.
LACP ensures only compatible and operational links are included in a bundle, maintaining network reliability and preventing misconfigurations.
