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. |
|
STP/RSTP/MSTP |
| Provides low convergence on a large network, which cannot meet the carrier-class reliability requirement. |
SEP |
| Is a Huawei proprietary protocol that cannot be used for communication between Huawei and non-Huawei devices. |
ERPS |
| 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.
