1.2组网拓扑
说明:
目前现网两台AC分别侧挂在锦业路和崇业路两台BAS,热点AP采用三层隧道模式的组网方式,这种组网模式已经不能满足业务的发展需求。
为了达到链路和设备级冗灾需求,出现故障时客户仍能无感知的享受网络,需要把现网改造为双机热备模式。
本指导书以如下拓扑和端口关系为基础,详细描述AC双机热备部署。
1.3业务部署需求
1.3.1AC热备规划
根据现网情况,本次热备规划使用目前成熟的独享地址池+网络侧隧道迂回方案进行部署,针对WLAN业务实现热备。
WLAN-AC组网及IP地址分配:
1.主备AC各配置2个聚合组Trunk-1和Trunk-2。
Trunk-1用于和BAS互联;
Trunk-2用于两台AC互联;
2.AC侧Trunk-1需要配置3个子接口,分别终结公网地址、内网1地址、内网2地址。
子接口与封装VLAN保持一致。
VLAN规划为:
1001,1002,1003,1004
VLAN1001用于VRRP主AC:
192.168.1.2/29备AC:
192.168.1.3/29Virtual-ip192.168.1.1
VLAN1002、1004用于AC与BAS公网互联
主AC地址:
211.137.138.234/30BAS地址:
211.137.138.233/30
备AC地址:
211.137.138.238/30BAS地址:
211.137.138.237/30
VLAN1003用户AP管理地址互联:
172.16.218.43/29BAS地址:
172.16.218.41/29
172.16.218.42/29BAS地址:
3.主备AC各使用一个32位地址,用于设备管理。
LoopBack0
主AC:
120.192.243.47/32备AC:
120.192.243.48/32
4.主备AC使用相同的NAS-IP32位地址。
LoopBack100
211.137.138.122/32备AC:
211.137.138.122/32
5.内网地址1使用29掩码地址段,启用VRRP协议。
用于AC主备的区分。
6.内网地址2使用29掩码地址段,用户AP管理的接口地址,用于建立CAPWAP隧道。
7.AP管理地址池:
192.168.12.1/24
8.用户业务地址池:
111.20.61.1/24
以上部分数据域现网不一致,仅用于举例
1.3.2路由规划
1.AC与Bras之间运行OSPF路由发布用户地址段和NAS-IP(L1地址),并且备AC发布的NAS-IP的cost值大,详见如下配置指导。
OSPF路由

AC使用管理地址做ROUTER-ID.

路由发布
IP城域网BAS向AC发布缺省路由default-always;
AC仅向IP城域网汇聚路由器发布该AC下的业务网段和互联网段。
