ERPS into rep topology

[AhmedLatif41843]

Hi 

I have ERPS ring network consist of 20 non cisco switches and i have cisco C9500 switch, As i read data sheet C9500 does not support ERPS protocol, is there any way to get ERPS protocol in C9500 switches or using REP protocol to integrated in ERPS ring network ? 

Regards

this post  Solved: ERPS support - Cisco Community 
with links from @Mark Elsen says it is supported  using IOS-XE 16.

Hi Pieterh

Thank you for reply, I read this solution it does not clear my concept.
If I configured REP protocol on C9500 interfaces and plug ERPS-link coming from other non cisco switch, will it work ? 
Ring topolgy will complete ?

sorry I have no practical experience in this matter, so I cannot give you a conclusive answer

Bing chat gives the response below, but unfortunately the linked document ( same as in my posts above) do not mention ERPS explicitly.

Yes, it is possible to connect an ERPS ring to a Cisco 9500 REP configuration
Resilient Ethernet Protocol (REP) is a Cisco proprietary protocol that provides an alternative to Spanning Tree Protocol (STP) to control network loops, handle link failures, and improve convergence time 1. REP controls a group of ports connected in a segment, ensures that the segment does not create any bridging loops, and responds to link failures within the segment. REP provides a basis for constructing more complex networks and supports VLAN load balancing 1.

On the other hand, Ethernet Ring Protection Switching (ERPS) is a standard protocol that provides sub-50ms protection and recovery switching for Ethernet traffic in ring topologies 1. ERPS can be configured on Cisco switches, including the Catalyst 9500 series switches 1.

To configure ERPS on a Cisco switch, you can refer to the Cisco IOS XE Gibraltar 16.12.x Layer 2 Configuration Guide 1. The guide provides detailed information on how to configure ERPS on Catalyst 9500 switches, including how to configure a ring segment, how to configure a node ID, and how to configure ERPS attributes 1.

Ok i will check with cisco rep n non cisco ERPS and update in this post.

Thank you for your support.

Ahmed, hi

Have you tested G8032 compitability with REP? 

Doest it work properly?
