53-RRPP典型配置举例
本章节下载： 53-RRPP典型配置举例 (445.65 KB)
目 录
本章主要介绍了通过在以太网环上配置RRPP功能，可以实现在以太网环完整时能够防止数据环路引起的广播风暴，而当以太网环上一条链路断开时能迅速恢复环网上各个节点之间的通信通路，使网络具备较高的收敛速度。
· 不建议在RRPP端口上启用以太网OAM远端环回功能，否则可能引起短时间的广播风暴。仅S5820X&S5800系列以太网交换机和S5500-EI&S5500-SI系列以太网交换机支持以太网OAM远端环回功能。
· 控制VLAN上不能运行QinQ（802.1Q in 802.1Q）和VLAN映射功能，否则RRPP协议报文无法正常收发。
· RRPP端口的端口类型只能是二层以太网端口或二层聚合接口，但当二层以太网端口是二层聚合组、业务环回组或Smart Link组的成员端口时除外。
· 接入RRPP环的端口必须关闭STP功能，且不能开启Smart Link功能。
· 为了以提高RRPP的拓扑变化收敛速度，建议在RRPP端口上不要配置端口的物理连接状态up/down抑制时间。

如图1-1所示，多个小区用户接入汇聚层网络，该汇聚层网络采用环网结构。
现要求在该环网上配置RRPP功能，实现：
· 当Ring 1物理连接完整时，各节点之间能够通信且不会存在数据环路引起的广播风暴。
· 当Ring 1上一条链路断开后，能迅速恢复环网上各个节点之间的通信通路，具备较高的收敛速度。
· 当Ring 1上断开的链路恢复后，该链路能够重新承载数据流量，且环网不存在环路现象。
图1-1 RRPP单环拓扑组网示意图
由于主节点是环网状态主动检测机制的发起者和网络拓扑发生改变后执行操作的决策者，需要选择性能较强大的设备作为主节点，本案例选择Device A作为主节点。
· 为避免由于关闭STP功能而造成的环路问题，请在完成环网内所有设备的RRPP配置后，再进行环网的完全连接。
· 为了激活当前设备的RRPP域，必须同时开启RRPP协议和RRPP环。
· 为了确保端口对RRPP协议报文的处理优先于数据报文，请将所有接入RRPP环的端口的信任模式配置为信认报文的802.1p优先级。对于S5820X&S5800、S5500-EI&S5500-SI系列以太网交换机，配置方法为在以太网端口视图下执行qos trust dot1p命令；对于S10500系列以太网交换机，配置方法为在以太网端口视图下执行undo qos trust命令（缺省情况下为信任报文的802.1p优先级，可以无需配置）。

如图1-2所示，接入层设备Device E以环网形式接入汇聚层，汇聚层也采用环网结构。
现要求在该环网上配置RRPP功能，实现：
· 当Ring 1或Ring 2物理连接完整时，该环的各节点之间能够通信且不会存在数据环路引起的广播风暴。
· 当Ring 1或Ring 2上一条链路断开后，能迅速恢复环网上各个节点之间的通信通路，具备较高的收敛速度。
· 当Ring 1或Ring 2上断开的链路恢复后，该链路能够重新承载数据流量，且环网不存在环路现象。
图1-2 RRPP相交环拓扑组网示意图
· 主环需要透传子环的保护VLAN和控制VLAN内的流量，需要有较强的数据传输能力。本案例选择Ring 1作为该RRPP域的主环，Ring 2则作为子环。
· 对于主环而言，需要选择性能较强大的设备作为主节点；对于子环而言，选择除两环的公共节点外的设备作为主节点。本案例选择Device A作为Ring 1的主节点和Device B作为Ring 2的主节点。
· 为避免由于关闭STP功能而造成的环路问题，请在完成环网内所有设备的RRPP配置后，再进行环网的完全连接。
· 为了激活当前设备的RRPP域，必须同时开启RRPP协议和RRPP环。
· 为避免子环的Hello报文在主环上形成环路，在子环的主节点上开启子环之前，请先在主环的主节点上开启主环。在边缘节点和辅助边缘节点上，需对主环和子环分别进行操作：开启子环前必须先开启主环。
· 为了确保端口对RRPP协议报文的处理优先于数据报文，请将所有接入RRPP环的端口的信任模式配置为信认报文的802.1p优先级。对于S5820X&S5800、S5500-EI&S5500-SI系列以太网交换机，配置方法为在以太网端口视图下执行qos trust dot1p命令；对于S10500系列以太网交换机，配置方法为在以太网端口视图下执行undo qos trust命令（缺省情况下为信任报文的802.1p优先级，可以无需配置）。

如1-17所示，多台接入层设备以环网形式接入汇聚层，汇聚层也采用环网结构。
现要求在该环网上配置RRPP功能，能够使较为复杂的组网具有以下功能：
· 当以太网环完整时，各环的节点之间能够通信且不会存在数据环路引起的广播风暴。
· 当以太网环上一条链路断开时能迅速恢复环网上各个节点之间的通信通路，具备较高的收敛速度。
· 当以太网环上断开的链路恢复后，该链路能够重新承载数据流量，且环网不存在环路现象。
图1-3 RRPP双边双归属环拓扑组网示意图
· 当某个RRPP域内存在多个环公共相交于某个环时，选择公共环作为主环，其他环作为子环。本案例选择Ring 1作为主环，Ring 2~5作为子环。
· 对于主环而言，需要选择性能较强大的设备作为主节点；对于子环而言，选择除公共节点外的设备作为主节点。本案例选择Device A作为Ring 1的主节点，选择Device E、Device F、Device G和Device H作为各自子环的主节点。
· 为避免由于关闭STP功能而造成的环路问题，请在完成环网内所有设备的RRPP配置后，再进行环网的完全连接。
· 为了激活当前设备的RRPP域，必须同时开启RRPP协议和RRPP环。
· 为避免子环的Hello报文在主环上形成环路，在子环的主节点上开启子环之前，请先在主环的主节点上开启主环。在边缘节点和辅助边缘节点上，需对主环和子环分别进行操作：开启子环前必须先开启主环。
· 为了确保端口对RRPP协议报文的处理优先于数据报文，请将所有接入RRPP环的端口的信任模式配置为信认报文的802.1p优先级。对于S5820X&S5800、S5500-EI&S5500-SI系列以太网交换机，配置方法为在以太网端口视图下执行qos trust dot1p命令；对于S10500系列以太网交换机，配置方法为在以太网端口视图下执行undo qos trust命令（缺省情况下为信任报文的802.1p优先级，可以无需配置）。

如图1-4所示，两个接入层网络以环网形式通过相同的两台设备接入汇聚层，汇聚层网络也采用环网结构。
现要求在该环网上配置RRPP功能，实现：
· 具有一般RRPP相交环的高可靠性和较强的收敛性能。
· 流量的负载分担，即不同VLAN的流量沿不同的路径进行转发（VLAN 12的流量沿Ring 1和Ring 2所在的网络进行转发，VLAN 11的流量沿Ring 1和Ring 3所在的网络进行转发）。
· 减少Edge-Hello报文的收发数量。
图1-4 RRPP相交环负载分担拓扑组网示意图
· 为了实现不同VLAN的流量沿不同的路径进行转发，要求通过在同一个环网上配置多个RRPP域，使不同RRPP域发送不同VLAN的流量。本案例将Ring 1和Ring 3配置为Domain 1的主环和子环，将Ring 1和Ring 2配置为Domain 2的主环和子环。
· 主环需要透传子环的保护VLAN和控制VLAN内的流量，需要有较强的数据传输能力。本案例选择Ring 1作为Domain 1和Domain 2的主环，Ring 2和Ring 3则作为各自RRPP域内的子环。
· 对于主环而言，需要选择性能较强大的设备作为主节点；对于子环而言，选择除公共节点外的设备作为主节点。本案例选择Device A作为Ring 1的主节点，选择Device E和Device F、作为各自子环的主节点。
· 为了减少Edge-Hello报文的收发数量，用户可以采用环组机制，即将具有相同边缘节点／辅助边缘节点配置的一组子环加入环组。本案例将Ring 2和Ring 3加入同一个环组内。
· 为避免由于关闭STP功能而造成的环路问题，请在完成环网内所有设备的RRPP配置后，再进行环网的完全连接。
· 为了激活当前设备的RRPP域，必须同时开启RRPP协议和RRPP环。
· 为避免子环的Hello报文在主环上形成环路，在子环的主节点上开启子环之前，请先在主环的主节点上开启主环。在边缘节点和辅助边缘节点上，需对主环和子环分别进行操作：开启子环前必须先开启主环。
· 如果需要将激活的环加入环组，需要按照下述顺序进行操作：先在辅助边缘节点将环加入环组，再在边缘节点将环加入环组。
· 边缘节点环组和对应的辅助边缘节点环组的配置和激活状态必须相同。
· 为了确保端口对RRPP协议报文的处理优先于数据报文，请将所有接入RRPP环的端口的信任模式配置为信认报文的802.1p优先级。对于S5820X&S5800、S5500-EI&S5500-SI系列以太网交换机，配置方法为在以太网端口视图下执行qos trust dot1p命令；对于S10500系列以太网交换机，配置方法为在以太网端口视图下执行undo qos trust命令（缺省情况下为信任报文的802.1p优先级，可以无需配置）。

如表1-5所示，多个小区用户接入汇聚层网络，该汇聚层网络采用RRPP环网结构，其中Device B和Device C不支持RRPP。
现要求在该环网上配置RRPP快速检测功能，解决在RRPP的实际运用中，环网中存在某些设备由于不支持RRPP协议而无法感知到这些设备之间的链路故障，而只能通过RRPP超时机制进行链路切换，导致流量中断时间过长，不能满足用户毫秒级切换的问题。通过配置RRPP快速检测功能，使该环网同样具有高可靠性和较强的收敛性能。
图1-5 RRPP快速检测组网示意图
· 由于主节点是环网状态主动检测机制的发起者和网络拓扑发生改变后执行操作的决策者，需要选择性能较强大的设备作为主节点，本案例选择Device A作为主节点。
· 如果要在一台不支持RRPP的设备上透传RRPP协议报文，为了避免其它VLAN的报文可能通过透传进入控制VLAN，从而对RRPP环产生冲击，应保证该设备上只有接入RRPP环的那两个端口允许该RRPP环所对应控制VLAN的报文通过。
· 当S10500系列以太网交换机安装了EB类单板后，才能支持RRPP快速检测功能。
· S5800系列交换机支持RRPP快速检测功能，S5820X系列交换机不支持RRPP快速检测。需要特别说明的是，S5820X系列交换机与S5800系列交换机混合堆叠形成的IRF虚拟设备支持RRPP快速检测。
· 为避免由于关闭STP功能而造成的环路问题，请在完成环网内所有设备的RRPP配置后，再进行环网的完全连接。
· 为了激活当前设备的RRPP域，必须同时开启RRPP协议和RRPP环。
· 为了确保端口对RRPP协议报文的处理优先于数据报文，请将所有接入RRPP环的端口的信任模式配置为信认报文的802.1p优先级。对于S5820X&S5800系列以太网交换机，配置方法为在以太网端口视图下执行qos trust dot1p命令；对于S10500系列以太网交换机，配置方法为在以太网端口视图下执行undo qos trust命令（缺省情况下为信任报文的802.1p优先级，可以无需配置）。

如图1-6所示，接入层设备Device E不支持RRPP，采用Smart Link双上行组网接入汇聚层网络，汇聚层网络采用RRPP环网结构。
现要求在该环网上使用RRPP与Smart Link混合组网功能，解决Device E由于不支持RRPP而无法采用RRPP相交环的方式来提高接入层可靠性的问题。通过在环网上配置RRPP功能，在Device E上配置Smart Link功能，能够实现接入层和汇聚层的可靠性和较高的收敛性能。
图1-6 RRPP与Smart Link混合组网示意图
关于RRPP单环拓扑的配置思路的详细内容，请参见“1.3.3 配置思路”。
· 关于RRPP单环拓扑的配置注意事项的详细内容，请参见“1.3.4 配置注意事项”。
· 配置Smart Link组的成员端口时，需先手工关闭该端口，再关闭该端口的STP功能，待Smart Link组配置完成后，再开启该端口，以避免形成环路，导致广播风暴。
· 配置Device C和Device D时，建议在其与Smart Link组的成员端口直接相连的端口上关闭STP功能，以免由于网络拓扑改变时端口状态尚未迁移到Forwarding（转发状态）而导致Flush报文被丢弃。
· 为了保证Device C和Device D能够正常地接收到Flush报文并进行处理，需要在Device C和Device D上开启的接收处理Flush报文功能的控制VLAN和在Smart Link设备上开启的发送Flush报文功能的控制VLAN相同。
