环网问题

1.14  RRPP典型配置举例

1.14.1  单环配置举例

1. 组网需求

·     Device A～Device D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 A为主环的主节点，GigabitEthernet1/0/1和GigabitEthernet1/0/2分别为主、副端口；Device B、Device C和Device D为主环的传输节点，其各自的GigabitEthernet1/0/1和GigabitEthernet1/0/2分别为主、副端口。

3. 配置步骤

(1)     配置Device A

# 创建VLAN 1～30，将这些VLAN都映射到MSTI 1上，并激活MST域的配置。

<DeviceA> system-view

[DeviceA] vlan 1 to 30

[DeviceA] stp region-configuration

[DeviceA-mst-region] instance 1 vlan 1 to 30

[DeviceA-mst-region] active region-configuration

[DeviceA-mst-region] quit

# 分别在端口GigabitEthernet1/0/1和GigabitEthernet1/0/2上配置物理连接状态up/down抑制时间为0秒（即不抑制），关闭生成树协议，并将端口配置为Trunk端口且允许VLAN 1～30通过。

[DeviceA] interface gigabitethernet 1/0/1

[DeviceA-GigabitEthernet1/0/1] link-delay up 0

[DeviceA-GigabitEthernet1/0/1] link-delay down 0

[DeviceA-GigabitEthernet1/0/1] undo stp enable

[DeviceA-GigabitEthernet1/0/1] port link-type trunk

[DeviceA-GigabitEthernet1/0/1] port trunk permit vlan 1 to 30

[DeviceA-GigabitEthernet1/0/1] quit

[DeviceA] interface gigabitethernet 1/0/2

[DeviceA-GigabitEthernet1/0/2] link-delay up 0

[DeviceA-GigabitEthernet1/0/2] link-delay down 0

[DeviceA-GigabitEthernet1/0/2] undo stp enable

[DeviceA-GigabitEthernet1/0/2] port link-type trunk

[DeviceA-GigabitEthernet1/0/2] port trunk permit vlan 1 to 30

[DeviceA-GigabitEthernet1/0/2] quit

# 创建RRPP域1，将VLAN 4092配置为该域的主控制VLAN，并将MSTI 1所映射的VLAN配置为该域的保护VLAN。

[DeviceA] rrpp domain 1

[DeviceA-rrpp-domain1] control-vlan 4092

[DeviceA-rrpp-domain1] protected-vlan reference-instance 1

# 配置本设备为主环Ring 1的主节点，主端口为GigabitEthernet1/0/1，副端口为GigabitEthernet1/0/2，并开启该环。

[DeviceA-rrpp-domain1] ring 1 node-mode master primary-port gigabitethernet 1/0/1 secondary-port gigabitethernet 1/0/2 level 0

[DeviceA-rrpp-domain1] ring 1 enable

[DeviceA-rrpp-domain1] quit

# 开启RRPP协议。

[DeviceA] rrpp enable

(2)     配置Device B

# 创建VLAN 1～30，将这些VLAN都映射到MSTI 1上，并激活MST域的配置。

<DeviceB> system-view

[DeviceB] vlan 1 to 30

[DeviceB] stp region-configuration

[DeviceB-mst-region] instance 1 vlan 1 to 30

[DeviceB-mst-region] active region-configuration

[DeviceB-mst-region] quit

# 分别在端口GigabitEthernet1/0/1和GigabitEthernet1/0/2上配置物理连接状态up/down抑制时间为0秒（即不抑制），关闭生成树协议，并将端口配置为Trunk端口且允许VLAN 1～30通过。

[DeviceB] interface gigabitethernet 1/0/1

[DeviceB-GigabitEthernet1/0/1] link-delay up 0

[DeviceB-GigabitEthernet1/0/1] link-delay down 0

[DeviceB-GigabitEthernet1/0/1] undo stp enable

[DeviceB-GigabitEthernet1/0/1] port link-type trunk

[DeviceB-GigabitEthernet1/0/1] port trunk permit vlan 1 to 30

[DeviceB-GigabitEthernet1/0/1] quit

[DeviceB] interface gigabitethernet 1/0/2

[DeviceB-GigabitEthernet1/0/2] link-delay up 0

[DeviceB-GigabitEthernet1/0/2] link-delay down 0

[DeviceB-GigabitEthernet1/0/2] undo stp enable

[DeviceB-GigabitEthernet1/0/2] port link-type trunk

[DeviceB-GigabitEthernet1/0/2] port trunk permit vlan 1 to 30

[DeviceB-GigabitEthernet1/0/2] quit

# 创建RRPP域1，将VLAN 4092配置为该域的主控制VLAN，并将MSTI 1所映射的VLAN配置为该域的保护VLAN。

[DeviceB] rrpp domain 1

[DeviceB-rrpp-domain1] control-vlan 4092

[DeviceB-rrpp-domain1] protected-vlan reference-instance 1

# 配置本设备为主环Ring 1的传输节点，主端口为GigabitEthernet1/0/1，副端口为GigabitEthernet1/0/2，并开启该环。

[DeviceB-rrpp-domain1] ring 1 node-mode transit primary-port gigabitethernet 1/0/1 secondary-port gigabitethernet 1/0/2 level 0

[DeviceB-rrpp-domain1] ring 1 enable

[DeviceB-rrpp-domain1] quit

# 开启RRPP协议。

[DeviceB] rrpp enable

(3)     配置Device C

Device C的配置与Device B相似，配置过程略。

(4)     配置Device D

Device D的配置与Device B相似，配置过程略。

4. 验证配置

配置完成后，用户可以使用display命令显示各设备上RRPP的配置和运行情况。
