ERPS单环多实例负载分担配置举例

1. 组网需求 为了更高效得利用网络资源，使环网上不同链路的流量负载比较均匀，可以通过在环网上各节点配置ERPS协议，使得不同的VLAN流量走不同的链路。 Device A、Device B、Device C和Device D构成ERPS环1，在该环上配置两个实例。 Instance 1的Owner节点为Device A，PRL为Device A和Device B之间的链路，控制VLAN为VLAN 100，保护VLAN为VLAN 1～30。 Instance 2的Owner节点为Device C，其PRL为Device C和Device D之间的链路，控制VLAN为VLAN 110，保护VLAN为VLAN 31～60。
