项目名称：有线网络高可用实施方案
项目需求：RouterOS 或SecPathF1000-S 2台， H3C S5500核心交换机2台，汇聚层S5120千兆交换机2台。
项目目的：汇聚层--核心层--网关实现高可用。防止单台设备或者链路故障导致全局或者局部网络不可用 ，防止单点故障造成损失,同时
汇聚层核心层实现负载均衡。
网路拓扑图：
说明与实现：
1. 两台出口设备一主一备，防止单台(路由)故障导致全局网络不可用。
2. 两台S5500核心交换机负载均衡，同时防止单台(核心)设备故障导致局部网络不可用。核心交换机配置两条缺省路由(优先级不同)，
下一跳分别为两台Routeros IP，并与track项联动,在核心上开启nqa的icmp-echo监测功能，判断吓一跳路由是否可达。若不可达则
对应的缺省路由失效，启动另一缺省路由。
3.每台汇聚层交换机分别开启两个trunk并上行分别链接至两台核心交换机，防止单台(核心)设备故障导致局部网络不可用。
补充：
经过最近一段时间的考虑，遇到了一个比较男解决的问题： panabit的网桥设计。
panabit的每个网桥只能使用两个端口，一进一出。 每台核心都需要物理连接到两台RouterOS。
目前想到的有两个方案：
- 每台核心出两条线经过panabit连接到两台RouterOS，需要四个网桥8个端口。 缺点：这样panabit所有网桥都是用，网线增多，出了问题不好定位，走线乱。
- 每台核心出一条线连接到panabit，panabit接外网的线挂个傻瓜交换机分流到两台RouterOS。 这种方式理论上应该可以，但是我致电咨询panabit工程师，
工程师说不可以，不知道是不是没听清楚的原因。
综合布线：
P ： 主机房
S1： 从1机房
S2： 从2机房
汇聚层： 汇聚层设备分别放置在12F对应位置的机房，如S1区域的汇聚设备安装在12F-S1机房，S2区域的汇聚设备安装在12F-S2机房.
交换机统计：
| 机房位置 | 交换机数量 |
|---|---|
| 11F-S1 | 4 |
| 12F-S1 | 6 |
| 13F-S1 | 5 |
| 累计15台 | |
| 11F-S2 | 5 |
| 12F-S2 | 6 |
| 13F-S2 | 5 |
| 累计16台 |
拉线统计:
| 源机房 | 目的机房 | 拉线数量 |
|---|---|---|
| 12F-S1 | 13F-S1 | 5+3(预留)=8 |
| 11F-S1 | 4+4(预留)=8 | |
| 累计16条网线 | ||
| 12F-S2 | 13F-S2 | 5+3(预留)=8 |
| 11F-S2 | 5+3(预留)=8 | |
| 累计16条网线 |
所以拉线总数为：16+16=32条。

VRRP配置： 目前共有vlan 1(default), 2-3, 5-6, 9-10, 15-16, 20, 30, 36, 40, 50, 60, 70, 80,90-91, 100, 110, 114, 119- 120, 123, 130, 140, 150, 180-181, 185,190-191, 200, 220, 222, 240, 253,888, 2000,4092-4094, 计43个 vlan. 通过在一个 VRRP 备份组中创建多个 VRRP 备份组（分属于不同VLAN），在实现主备备份 VRRP 应用的同时实现 VRRP 备份组中交换机的负载分担(100网段以下 流量走CoreSW1，100网段以上 流量走CoreSW2,vlan 888为电信公网网段，不做高可用节省IP地址)
注：目前H3C部分高端交换机VRRP支持负载均衡模式，但是S5500不支持，只能选择负载分担了。
