H3C--堆叠（IRF）

拓扑图

配置流程

配置SW1与SW2堆叠

一、SW1：

shutdown 物理端口
配置堆叠优先级，优先级高的成为主设备
创建堆叠逻辑接口，将物理接口加入到堆叠逻辑接口中

二、SW1：

sysname SW1
#
irf member 1 priority 6
#
irf-port 1/1
port group interface FortyGigE1/0/53
port group interface FortyGigE1/0/54
#

三、SW2：

配置堆叠ID为2，保存并重启

irf member 1 renumber 2
#

重启完成后，将物理接口shutdown
创建堆叠逻辑接口，将物理接口加入到堆叠逻辑接口中

SW2：

sysname SW2
#
interface FortyGigE2/0/53
shutdown
#
interface FortyGigE2/0/54
shutdown
#
irf-port 2/2
port group interface FortyGigE2/0/53
port group interface FortyGigE2/0/54
#

注意：堆叠逻辑接口交叉相连

irf-port 1/1：第一个1代表堆叠ID，第二个1代表接口ID
irf-port 2/2：第一个2代表堆叠ID，第二个2代表接口ID
堆叠接口1与接口2相连

四、SW1：

将加入到堆叠逻辑接口的物理接口undo shutdown
保存配置
激活配置

int range FortyGigE 1/0/53 FortyGigE 1/0/54
undo shutdown
#
irf-port-configuration active
#

五、SW2：

将加入到堆叠逻辑接口的物理接口undo shutdown
保存配置
激活配置
交换机将自动重启

int range FortyGigE 2/0/53 FortyGigE 2/0/54
undo shutdown
#
irf-port-configuration active
#

重启后两台设备虚拟成一台设备

配置ACC1与ACC2堆叠

配置堆叠域为1（默认为0），其他步骤同上

irf domain 1
#

配置成功后

配置链路聚合

SW1和ACC1链路聚合

interface Bridge-Aggregation1
link-aggregation mode dynamic
#
interface Ten-GigabitEthernet1/0/49
port link-aggregation group 1
#
interface Ten-GigabitEthernet1/0/50
port link-aggregation group 1
#
interface Ten-GigabitEthernet2/0/49
port link-aggregation group 1
#
interface Ten-GigabitEthernet2/0/50
port link-aggregation group 1
#

查看聚合端口状态

SW1与ACC3间链路聚合

SW1：

interface Bridge-Aggregation2
link-aggregation mode dynamic
#
interface Ten-GigabitEthernet1/0/52
port link-aggregation group 2
#
interface Ten-GigabitEthernet2/0/51
port link-aggregation group 2
#

ACC3：

interface Bridge-Aggregation2
link-aggregation mode dynamic
#
interface Ten-GigabitEthernet1/0/51
port link-aggregation group 2
#
interface Ten-GigabitEthernet1/0/52
port link-aggregation group 2
#

SW1与R1之间三层链路聚合

除配置链路聚合外，还可以配置动态路由选择协议（如OSPF）

SW1：

interface Route-Aggregation1
ip address 10.1.100.1 255.255.255.0
link-aggregation mode dynamic
#
int range g1/0/1 g2/0/1
port link-mode route
port link-aggregation group 1
#

R1:

sysname R1
#
interface Route-Aggregation1
ip address 10.1.100.254 255.255.255.0
link-aggregation mode dynamic
#
int range GigabitEthernet 0/0/1 GigabitEthernet 0/0/2
port link-aggregation group 1
#
interface GigabitEthernet0/0/0
ip address 150.1.1.1 255.255.255.0
#

配置VLAN

SW1：

vlan 10
#
vlan 20
#
interface Vlan-interface10
ip address 10.1.10.254 255.255.255.0
#
interface Vlan-interface20
ip address 10.1.20.254 255.255.255.0
#
interface Bridge-Aggregation1
port link-type trunk
port trunk permit vlan 10 20
#
interface Bridge-Aggregation2
port link-type trunk
port trunk permit vlan 10 20
#

ACC1：

vlan 10
#
vlan 20
#
interface Bridge-Aggregation1
port link-type trunk
port trunk permit vlan 10 20
#
interface GigabitEthernet1/0/1
port access vlan 10
#
interface GigabitEthernet2/0/1
port access vlan 20
#

ACC3：

vlan 10
#
vlan 20
#
interface Bridge-Aggregation2
port link-type trunk
port trunk permit vlan 10 20
#
interface GigabitEthernet1/0/1
port access vlan 20
#
interface GigabitEthernet1/0/1
port access vlan 20
#

配置路由及NAT

R1：

ip route-static 0.0.0.0 0 150.1.1.254
ip route-static 10.1.0.0 16 10.1.100.1
#
acl basic 2000
rule 5 permit source 10.1.0.0 0.0.255.255
#
interface GigabitEthernet0/0/0
nat outbound 2000
#

SW1：

ip route-static 0.0.0.0 0 10.1.100.254
#

ISP：

interface GigabitEthernet0/0/0
ip address 150.1.1.254 255.255.255.0
#
interface LoopBack0
ip address 6.6.6.6 255.255.255.255
#
