This post explains what is the difference between RRPP/SEP/STP/ERPS. Please find them in the table featured below.

In the current networking, various loop protocols emerge in an endless stream. How should we choose? In the case of Huawei a switch, it supports the ERPS/SEP/STP/RRPP.

What is the difference between these loop protocols?


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.

RRPP and SEP are the private protocols in Huawei; in the case of SEP, we can use it on the safe city network.

STP can communicate with other non-Huawei devices, but its convergence is slow.

ERPS provides fast convergence, but if there are any intersecting rings, it only supports one down point.

Clearly explains the differences between these protocol families.

Small network stack may be a good choice.
