IE4300组成的主环和IE4100组成的两个子环，配置双归属环问题

是RRPP吗，配置可以参考：https://www.h3c.com/cn/d_202009/1338018_30005_0.htm

相交环配置举例

1. 组网需求

·     Device A～Device E构成RRPP域1，该域的主控制VLAN为VLAN 4092，保护VLAN为VLAN 1～30。

·     Device A、Device B、Device C和Device D构成主环Ring 1；Device B、Device C和Device E构成子环Ring 2。

·     Device A为主环的主节点，GigabitEthernet1/0/1和GigabitEthernet1/0/2分别为主、副端口；Device E为子环的主节点，GigabitEthernet1/0/1和GigabitEthernet1/0/2分别为主、副端口；Device B为主环的传输节点和子环的边缘节点，GigabitEthernet1/0/3为边缘端口；Device C为主环的传输节点和子环的辅助边缘节点，GigabitEthernet1/0/3为边缘端口；Device D为主环的传输节点，GigabitEthernet1/0/1和GigabitEthernet1/0/2分别为主、副端口。
