RouterOS使用Macvlan配置多拨的PCC负载均衡

RouterOS v7.12开始支持macvlan，意味着pppoe客户端单接口多拨，不再需要创建vrrp（vrrp无法修改mac地址）或者bridge方式来修改mac地址，可以使用macvlan来创建虚拟mac地址拨号，这样简化了操作配置，同样也减少了路由器开销。

下面的实例基于划分VLAN的方式进行拨号，pppoe接入在交换机上都设置一个单独的VLAN ID，然后通过trunk到RouterOS的sfp-sfpplus1接口，创建VLAN子接口后，进行拨号。

华为交换机配置

创建GigabitEthernet 0/0/1-GigabitEthernet 0/0/3的模式access，vlan id分别是10，20，30

[Huawei]interface GigabitEthernet 0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type access
[Huawei-GigabitEthernet0/0/1]port default vlan 10
[Huawei-GigabitEthernet0/0/1] interface GigabitEthernet 0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type access
[Huawei-GigabitEthernet0/0/2]port default vlan 20
[Huawei-GigabitEthernet0/0/2] interface GigabitEthernet 0/0/3
[Huawei-GigabitEthernet0/0/3]port link-type access
[Huawei-GigabitEthernet0/0/3]port default vlan 30

配置interface XGigabitEthernet0/1/1端口为Trunk口配置，设置vlan 10，20，30

[Huawei]interface interface XGigabitEthernet0/1/1
[Huawei-interface XGigabitEthernet0/1/1]port link-type trunk
[Huawei-interface XGigabitEthernet0/1/1]port trunk allow-pass vlan 10 20 30

RouterOS配置

配置sfp-sfpplus1接口的vlan子接口

/interface vlan
add interface=sfp-sfpplus1 name=vlan10 vlan-id=10
add interface=sfp-sfpplus1 name=vlan20 vlan-id=20
add interface=sfp-sfpplus1 name=vlan30 vlan-id=30

基于vlan10，vlan20，vlan30创建对应的macvlan接口，并设置固定mac地址

/interface macvlan
add interface=vlan10 mac-address=72:73:50:81:27:10 mode=private name=macvlan10
add interface=vlan20 mac-address=72:73:50:81:27:20 mode=private name=macvlan20
add interface=vlan30 mac-address=72:73:50:81:27:30 mode=private name=macvlan30

创建PPPoE拨号接口到对应的macvlan

/interface pppoe-client
add disabled=no interface=macvlan10 name=pppoe-out1 user=yus
add disabled=no interface=macvlan20 name=pppoe-out2 user=yus
add disabled=no interface=macvlan30 name=pppoe-out3 user=yus

剩下的是需要创建3条PCC规则，可以通过本站的脚本生成器配置，选择RouterOS v7，（PCC脚本生成）

生成如下：
