Chapter 7 Reliability Configuration

As shown in the picture above, it is the explanation of ERPS configuration and

application. S1~S4 make up the ring network and provide the layer2 redundancy

protection transform function. For preventing the packets in VLAN10 ~ VLAN20 come to

be loop, deploy the ERPS protocol on the devices which make up the ring network. The

forwarding path of user data inserted through CE1 is S2-S1 and it is S3-S4 for the data

which is deserted through CE2. For protecting the Ethernet loop switching, configure it as

below:

1. Configuration thinking

Configure ERPS loop redundancy protection as below:

Create ERPS loop of maijor_ring1 and configure the loop member port;

Configure the instance 1 on ERPS loop of maijor_ring1 and configure the protection

instance, member port role, timer and controlling VLAN.

2. Configuration steps

Step1: Create instance 2, VLAN2 and VLAN10-20 on S1 ~ S4, VLAN2 is used to

transmit the protocol packets, VLAN10-20 are used to transmit the data packets.
