配置RRPP单实例单环示例
组网需求
如图18-32所示,在组网中存在由SwitchA、SwitchB、SwitchC组成的环网结构。对于这种组网结构,需要当环网完整时,可以避免报文成环;当环网发生故障时,可以实现快速收敛迅速恢复环网上各节点间的通信。在SwitchA、SwitchB和SwitchC上配置RRPP功能,可以很好地满足这两个需求。
配置思路
采用如下的思路配置RRPP单环示例:
配置设备上将要加入RRPP的各接口,使其可以通过RRPP环上需要通过的VLAN数据,并去使能与RRPP相冲突的功能(例如STP功能)。
创建RRPP域和控制VLAN,为后续配置RRPP环做好准备。
将RRPP环上需要通过的VLAN数据映射到实例1,包括数据VLAN100~VLAN300和控制VLAN20、VLAN21(其中VLAN21是设备自动生成的子控制VLAN),为后续配置保护VLAN做好准备。
在RRPP域中,配置保护VLAN并创建RRPP环,将SwitchA、SwitchB和SwitchC配置为域1环1的节点。其中配置SwitchA为环1的主节点,SwitchB和SwitchC为环1的传输节点。
在各设备上使能RRPP环和RRPP协议,使得RRPP功能生效。
操作步骤
- 创建RRPP域,同时创建域的控制VLAN
# 配置SwitchA。SwitchB和SwitchC的配置与SwitchA类似,此处省略,详见配置文件。
<HUAWEI> system-view [HUAWEI] sysname SwitchA [SwitchA] rrpp domain 1 [SwitchA-rrpp-domain-region1] control-vlan 20 [SwitchA-rrpp-domain-region1] quit
- 配置实例1映射控制VLAN20、VLAN21和数据VLAN100~VLAN300。
# 配置SwitchA。SwitchB和SwitchC的配置与SwitchA相同,此处省略,详见配置文件。
[SwitchA] vlan batch 100 to 300 [SwitchA] stp region-configuration [SwitchA-mst-region] instance 1 vlan 20 21 100 to 300 [SwitchA-mst-region] active region-configuration [SwitchA-mst-region] quit
- 将即将加入RRPP环的接口配置为Trunk类型接口,允许VLAN100~300通过,并去使能接口的STP功能
# 配置SwitchA。SwitchB和SwitchC的配置与SwitchA相同,此处省略,详见配置文件。
[SwitchA] interface gigabitethernet 2/0/1 [SwitchA-GigabitEthernet2/0/1] port link-type trunk [SwitchA-GigabitEthernet2/0/1] undo port trunk allow-pass vlan 1 [SwitchA-GigabitEthernet2/0/1] port trunk allow-pass vlan 100 to 300 [SwitchA-GigabitEthernet2/0/1] stp disable [SwitchA-GigabitEthernet2/0/1] quit [SwitchA] interface gigabitethernet 2/0/2 [SwitchA-GigabitEthernet2/0/2] port link-type trunk [SwitchA-GigabitEthernet2/0/2] undo port trunk allow-pass vlan 1 [SwitchA-GigabitEthernet2/0/2] port trunk allow-pass vlan 100 to 300 [SwitchA-GigabitEthernet2/0/2] stp disable [SwitchA-GigabitEthernet2/0/2] quit
- 配置保护VLAN,创建RRPP环并使能RRPP环
# 配置SwitchA。
[SwitchA] rrpp domain 1 [SwitchA-rrpp-domain-region1] protected-vlan reference-instance 1 [SwitchA-rrpp-domain-region1] ring 1 node-mode master primary-port gigabitethernet 2/0/1 secondary-port gigabitethernet 2/0/2 level 0 [SwitchA-rrpp-domain-region1] ring 1 enable [SwitchA-rrpp-domain-region1] quit
# 配置SwitchB。
[SwitchB] rrpp domain 1 [SwitchB-rrpp-domain-region1] protected-vlan reference-instance 1 [SwitchB-rrpp-domain-region1] ring 1 node-mode transit primary-port gigabitethernet 2/0/1 secondary-port gigabitethernet 2/0/2 level 0 [SwitchB-rrpp-domain-region1] ring 1 enable [SwitchB-rrpp-domain-region1] quit
# 配置SwitchC。
[SwitchC] rrpp domain 1 [SwitchC-rrpp-domain-region1] protected-vlan reference-instance 1 [SwitchC-rrpp-domain-region1] ring 1 node-mode transit primary-port gigabitethernet 2/0/1 secondary-port gigabitethernet 2/0/2 level 0 [SwitchC-rrpp-domain-region1] ring 1 enable [SwitchC-rrpp-domain-region1] quit
- 使能RRPP协议
# 配置SwitchA。SwitchB和SwitchC的配置与SwitchA相同,此处省略,详见配置文件。
[SwitchA] rrpp enable
- 检查配置结果
经过以上配置,在网络稳定后,执行以下操作,验证配置结果。以SwitchA为例。
# 在SwitchA上执行display rrpp brief命令,查看结果如下:
[SwitchA] display rrpp brief Abbreviations for Switch Node Mode : M - Master , T - Transit , E - Edge , A - Assistant-Edge RRPP Protocol Status: Enable RRPP Working Mode: HW RRPP Linkup Delay Timer: 0 sec (0 sec default) Number of RRPP Domains: 1 Domain Index : 1 Control VLAN : major 20 sub 21 Protected VLAN : Reference Instance 1 Hello Timer : 1 sec(default is 1 sec) Fail Timer : 6 sec(default is 6 sec) Ring Ring Node Primary/Common Secondary/Edge Is ID Level Mode Port Port Enabled ---------------------------------------------------------------------------- 1 0 M GigabitEthernet2/0/1 GigabitEthernet2/0/2 Yes
可以看到SwitchA的RRPP协议状态使能了,在域1中的主控制Vlan为20,子控制Vlan为21,SwitchA为主环1中的主节点。主端口为GigabitEthernet2/0/1,副端口为GigabitEthernet2/0/2。
# 在SwitchA上执行display rrpp verbose domain命令,查看结果如下:
[SwitchA] display rrpp verbose domain 1 Domain Index : 1 Control VLAN : major 20 sub 21 Protected VLAN : Reference Instance 1 Hello Timer : 1 sec(default is 1 sec) Fail Timer : 6 sec(default is 6 sec) RRPP Ring : 1 Ring Level : 0 Node Mode : Master Ring State : Complete Is Enabled : Enable Is Active: Yes Primary port : GigabitEthernet2/0/1 Port status: UP Secondary port : GigabitEthernet2/0/2 Port status: BLOCKED
可以看到RRPP环的状态处于完整状态。
