这2个的功能感觉有点相像,具体上有什么区别呢?以太网冗余接口是H3C的私有协议么?
冗余接口用在那种场景呢?
上面这个拓扑,冗余接口可以看作是一个逻辑接口,下联核心交换机,核心交换机上的这个端口怎么配ip地址呢?是将这2个端口划入同一个vlan吗?

最佳答案
您好,请知:
下行的三层交换机需要创建VLAN,并设置VLAN IP,同时将VLAN划分到端口。
关于冗余口的配置,可参考如下配置举例:
· 如图2-7所示,Device A和Device B组成IRF,Device A和Device B分别用一个接口连接上行设备Device C,再分别用一个接口连接下行设备Device D。
· Device C使用VLAN接口连接Device A和Device B,Device D也使用VLAN接口连接Device A和Device B。
· 正常情况下,流量走Device D——Device A——Device C;当这条通道上的任一链路或者设备故障时,流量切换到Device D——Device B——Device C。正常通道故障恢复时,流量再切回。
(1) 配置各接口的IP地址、路由、安全域及域间策略保证网络可达,具体配置过程略。
(2) 配置IRF
IRF的配置请参见“2.13.2 工作在三层,上下行分别连接一台设备”。
(3) 配置以太网冗余接口
# 创建Reth1,IP地址为1.1.1.2/24,成员接口为GigabitEthernet1/0/1和GigabitEthernet2/0/1,其中GigabitEthernet1/0/1的优先级为255,GigabitEthernet2/0/1的优先级为50。
<Sysname> system-view
[Sysname] interface reth 1
[Sysname-Reth1] ip address 1.1.1.2 24
[Sysname-Reth1] member interface gigabitethernet 1/0/1 priority 255
[Sysname-Reth1] member interface gigabitethernet 2/0/1 priority 50
[Sysname-Reth1] quit
# 创建Reth2,IP地址为2.2.2.2/24,成员接口为GigabitEthernet1/0/2和GigabitEthernet2/0/2,其中GigabitEthernet1/0/2的优先级为255,GigabitEthernet2/0/2的优先级为50。
[Sysname] interface reth 2
[Sysname-Reth2] ip address 2.2.2.2 24
[Sysname-Reth2] member interface gigabitethernet 1/0/2 priority 255
[Sysname-Reth2] member interface gigabitethernet 2/0/2 priority 50
[Sysname-Reth2] quit
(4) 配置Track,监测上、下行接口的状态。
[Sysname] track 1 interface gigabitethernet 1/0/1 physical
[Sysname-track-1] quit
[Sysname] track 2 interface gigabitethernet 1/0/2 physical
[Sysname-track-2] quit
[Sysname] track 3 interface gigabitethernet 2/0/1 physical
[Sysname-track-3] quit
[Sysname] track 4 interface gigabitethernet 2/0/2 physical
[Sysname-track-4] quit
(5) 配置冗余组
# 创建Node 1,Node 1和Device A绑定,为主节点。关联的Track项为1和2。
[Sysname] redundancy group aaa
[Sysname-redundancy-group-aaa] node 1
[Sysname-redundancy-group-aaa-node1] bind slot 1
[Sysname-redundancy-group-aaa-node1] priority 100
[Sysname-redundancy-group-aaa-node1] track 1 interface gigabitethernet 1/0/1
[Sysname-redundancy-group-aaa-node1] track 2 interface gigabitethernet 1/0/2
[Sysname-redundancy-group-aaa-node1] quit
# 创建Node 2,Node 2和Device B绑定,为备节点。关联的Track项为3和4。
[Sysname-redundancy-group-aaa] node 2
[Sysname-redundancy-group-aaa-node2] bind slot 2
[Sysname-redundancy-group-aaa-node2] priority 50
[Sysname-redundancy-group-aaa-node2] track 3 interface gigabitethernet 2/0/1
[Sysname-redundancy-group-aaa-node2] track 4 interface gigabitethernet 2/0/2
[Sysname-redundancy-group-aaa-node2] quit
# 将Reth1和Reth2添加到冗余组中。
[Sysname-redundancy-group-aaa] member interface reth 1
[Sysname-redundancy-group-aaa] member interface reth 2
[Sysname-redundancy-group-aaa] quit
(1) 缺省情况下的显示信息
# 显示冗余组信息。可以看到优先级高的Node 1为主节点,Reth1和Reth2中优先级高的成员接口处于激活状态。
[Sysname] display redundancy group aaa
Redundancy group aaa (ID 1):

Node2 Slot2 50 Secondary 255

[Sysname] display reth interface reth 2

(2) 冗余组内主备倒换后的显示信息
# 手工关闭接口GigabitEthernet1/0/2,显示冗余组信息。可以看到优先级低的Node 2为主节点。
[Sysname] interface gigabitethernet 1/0/2
[Sysname-GigabitEthernet1/0/2] shutdown
[Sysname-GigabitEthernet1/0/2] display redundancy group aaa
Redundancy group aaa (ID 1):
Node ID Slot Priority Status Track weight
Node1 Slot1 100 Secondary -255
Node2 Slot2 50 Primary 255
Preempt delay time remained : 0 min
Preempt delay timer setting : 1 min
