[S1]dis irf

  *1        Master  1         7420-b83d-0100  ---

  +2        Standby 1         7420-bdd9-0200  ---

--------------------------------------------------

 * indicates the device is the master.

 + indicates the device through which the user logs in.


 The Bridge MAC of the IRF is: 7420-b83d-0100

 Auto upgrade                : yes

 Mac persistent              : 6 min

 Domain ID                   : 0


注意设备名称

[S1]int GigabitEthernet 1/0/2 这儿不需要创建聚合端口,因为R1和R2虚拟成一个设备,R1上创建了

[S1-GigabitEthernet1/0/2]port link-aggregation group 2

[S1-GigabitEthernet1/0/2]quit

R3配置:

[S3]interface Bridge-Aggregation 2

[S3-Bridge-Aggregation2]link-aggregation mode dynamic

[S3-Bridge-Aggregation2]quit

[S3]int g1/0/1

[S3-GigabitEthernet1/0/1]port link-aggregation group 2

[S3-GigabitEthernet1/0/1]quit

[S3]int g1/0/2

[S3-GigabitEthernet1/0/2]port link-aggregation group 2

[S3-GigabitEthernet1/0/2]quit



IRF域编号:

[S2]irf member 1 renumber 2  修改成员编号为2

注意:修改完成之后需要重启才有效

[S2]save 保存配置

<S2>reboot 重启 


配置成员优先级:

[S1]irf member 1 priority 10

1.成员优先级是成员设备的一个属性,主要用于角色选举过程中确定成员设备的角色。优先级越高当选为Master的可能性越大

2.设备的缺省优先级均为1,如果想让某台设备当选为Master,则在组建IRF前,可以通过命令行手工提高该设备的成员优先级


配置负载分担:

  1. 全局配置:

    [S1]irf-port global load-sharing mode destination-mac source-mac

  2. 接口配置:

    [S1]irf-port 1/2

    [S1-irf-port1/2]irf-port load-sharing mode source-ip destination-ip


启动自动加载功能:

[S1]irf auto-update enable


配置BFD MAD检测:

# 创建VLAN 3,并将SW2上的端口Gthernet1/0/1和SW3上的端口Gthernet1/0/1加入VLAN中。

<SW2> system-view

[SW2] vlan 3

[SW2-vlan3] port ethernet 1/0/1 ethernet 1/0/1

[SW2-vlan3] quit

# 创建VLAN接口3,并配置MAD IP地址。

[SW2] interface vlan-interface 3

[SW2-Vlan-interface3] mad bfd enable

[SW2-Vlan-interface3] mad ip address 192.168.2.1 24 member 1

[SW2-Vlan-interface3] mad ip address 192.168.2.2 24 member 2

[SW2-Vlan-interface3] quit

# 按图1-14所示连接BFD MAD链路。

# 因为BFD MAD和生成树功能互斥,所以在Gthernet1/0/1和Gthernet1/0/1上关闭生成树协议。

[SW2] interface ethernet 1/0/1

[SW2-Ethernet1/0/1] undo stp enable

[SW2-Ethernet1/0/1] quit

[SW2] interface ethernet 2/0/1

[SW2-Ethernet2/0/1] undo stp enable


配置ARP MAD:

# 在IRF上全局使能MSTP,以防止环路的发生。

<SW2> system-view

[SW2] stp enable

# 按图1-15所示连接ARP MAD检测链路。

# 将IRF配置为MAC地址立即改变。

[SW2] undo irf mac-address persistent

# 创建VLAN 3,并将Device A(成员编号为1)上的端口gthernet1/0/1和Device B(成员编号为2)上的端口Ethernet2/0/1加入VLAN中。

{SW2] vlan 3

[SW2-vlan3] port ethernet 1/0/1 ethernet 2/0/1

[SW2-vlan3] quit

# 创建VLAN-interface3,并配置IP地址,使能ARP MAD检测功能,由于并不是在两个IRF之间配置ARP MAD检测,因此在系统提示输入IRF域ID时,可以保持为默认值0。

[SW2] interface vlan-interface 3

[SW2-Vlan-interface3] ip address 192.168.2.1 24

[SW2-Vlan-interface3] mad arp enable

 You need to assign a domain ID (range: 0-4294967295)

 [Current domain is: 0]:

 The assigned  domain ID is: 0

(5)配置SW1

# 在全局使能MSTP,以防止环路的发生。

<SW1> system-view

[SW1] stp enable

# 创建VLAN 3,并将端口Gthernet1/0/1和Gthernet1/0/2加入VLAN 3中,用于转发ARP MAD报文。

[SW1] vlan 3

[SW1-vlan3] port Gthernet 1/0/1 Gthernet 1/0/2

[SW1-vlan3] quit
