Configuring ERPS Multi-instance
Applicable Products and Versions
This example applies to the CE12800 V100R003C00 or later, the CE12800E configured with FD-X series cards V200R005C00 or later, the CE8800 V100R006C00 or later and the CE7800/CE6800/CE5800 (excluding CE5880EI and CE6880EI) V100R003C10 or later.
Networking Requirements
Figure 2-29 shows SwitchA through SwitchC constitute a ring network at the aggregation layer to implement service aggregation at Layer 2 and process Layer 3 services. ERPS is used on the ring network to provide protection switching for Layer 2 redundant links. ERPS ring 1 and ERPS ring 2 are configured on SwitchA through SwitchC. Eth-Trunk2 on SwitchA is a blocked port in ERPS ring 1, and Eth-Trunk3 on SwitchB is a blocked port in ERPS ring 2, implementing load balancing and link backup.
Configuration Roadmap
Configure the link type of all ports to be added to ERPS rings as trunk.
Create ERPS rings and configure control VLANs and Ethernet Ring Protection (ERP) instances in the ERPS rings.
Add Layer 2 ports to ERPS rings and specify port roles.
Configure the Guard timers and WTR timers in the ERPS rings.
Configure Layer 2 forwarding on SwitchA through SwitchC.
Procedure
- Configure the link type of all ports to be added to an ERPS ring as trunk.

- Create ERPS ring 1 and ERPS ring 2 and configure ERP instances in the two rings. Set the control VLAN ID of ERPS ring 1 to 10 and the control VLAN ID of ERPS ring 2 to 20. Enable ERPS ring 1 to transmit data packets from VLANs 100 to 200 and enable ERPS ring 2 to transmit data packets from VLANs 300 to 400.
![]()
A VLAN cannot be mapped to multiple MSTIs. If you map a VLAN that has already been mapped to an MSTI to another MSTI, the original mapping will be deleted.
