What is the difference between RRPP/SEP/STP/ERPS?

RRPP

Provides fast convergence and carrier-class reliability.

• Supports only level-1 sub-ring in ring networking.

• Is a Huawei proprietary protocol that cannot be used for communication between Huawei and non-Huawei devices.

STP/RSTP/MSTP

• Applies to all Layer 2 networks.

• Is a standard IEEE protocol that allows Huawei devices to communicate with non-Huawei devices.

Provides low convergence on a large network, which cannot meet the carrier-class reliability requirement.

SEP

• Applies to all Layer 2 networks.

• Provides fast convergence and carrier-class reliability.

• Displays the topology of an entire ring, facilitating fault location and device maintenance.

Is a Huawei proprietary protocol that cannot be used for communication between Huawei and non-Huawei devices.

ERPS

• Provides fast convergence and carrier-class reliability.

• Is a standard ITU-T protocol that allows Huawei devices to communicate with non-Huawei devices.

• Supports single-ring and multi-ring topologies in ERPSv2.

Requires the network topology to be planned in advance. The configuration is complex.
