问题描述
拓扑如下:

9303的配置:

interface GigabitEthernet4/0/1
port link-type trunk
port trunk allow-pass vlan 8 301 to 380 401 to 480 1401 to 1440 1501 to 1600
stp disable
interface GigabitEthernet4/0/2
port link-type trunk
port trunk allow-pass vlan 8 301 to 380 401 to 480 1401 to 1440 1501 to 1600
stp disable
rrpp domain 1
protected-vlan reference-instance 1
control-vlan 96
rrpp domain 2
protected-vlan reference-instance 2
control-vlan 98
rrpp domain 1
ring 1 node-mode master primary-port GigabitEthernet4/0/1 secondary-port GigabitEthernet4/0/2 level 0
ring 1 enable
rrpp domain 2

ring 1 node-mode master primary-port GigabitEthernet4/0/2 secondary-port GigabitEthernet4/0/1 level 0
ring 1 enable
rrpp enable

5700-1 的配置:

 stp region-configurationi
 instance 1 vlan 96 97 401 to 480
 instance 2 vlan 98 99 301 to 380 1401 to 1440 1501 to 1600
 active region-configuration
 quit
interface XGigabitEthernet0/1/1
port link-type trunk
port trunk allow-pass vlan 8  301 to 380 401 to 480 1401 to 1440 1501 to 1600
stp disable
Quit
interface XGigabitEthernet0/1/2
port link-type trunk
port trunk allow-pass vlan 8  301 to 380 401 to 480 1401 to 1440 1501 to 1600
stp disable
quit
rrpp domain 1
protected-vlan reference-instance 1
control-vlan 96
 quit
rrpp domain 2
protected-vlan reference-instance 2
control-vlan 98
  Quit

rrpp domain 1
ring 1 node-mode transit primary-port XGigabitEthernet 0/1/1 secondary-port XGigabitEthernet 0/1/2 level 0
ring 1 enable
quit

rrpp domain 2
ring 1 node-mode transit primary-port XGigabitEthernet 0/1/1 secondary-port XGigabitEthernet 0/1/2 level 0
ring 1 enable
rrpp enable

5700-2的配置:

stp region-configuration
instance 1 vlan 96 97 8 401 to 480
instance 2 vlan 98 99 301 to 380 1401 to 1440 1501 to 1600
active region-configuration

interface GigabitEthernet0/0/1
port link-type trunk
port trunk allow-pass vlan 8 301 to 380 401 to 480 1401 to 1440 1501 to 1600
stp disable

interface GigabitEthernet0/0/2
port link-type trunk
port trunk allow-pass vlan 8 301 to 380 401 to 480 1401 to 1440 1501 to 1600
stp disable

rrpp domain 1
protected-vlan reference-instance 1
control-vlan 96
rrpp domain 2
protected-vlan reference-instance 2
control-vlan 98
rrpp domain 1
ring 1 node-mode transit primary-port XGigabitEthernet 0/1/1 secondary-port XGigabitEthernet 0/1/2 level 0
ring 1 enable
rrpp domain 2
ring 1 node-mode transit primary-port XGigabitEthernet 0/1/1 secondary-port XGigabitEthernet 0/1/2 level 0
ring 1 enable
rrpp enable

配置完成后互连的接口流量异常,超过正常流量的数倍
处理过程
通过下列的命令确认了RRPP的配置和状态都正确  display rrpp statistics   display rrpp brief  抓包发现有大量的的广播报文。
根因
trunk端口默认透传了Vlan1的数据流量,而Vlan未加入到任何的实例
解决方案
互联接口上拒绝Vlan1的数据流量通过或者将Vlan1 加入到实例中
