重要说明

1、在一台ac中实现三层漫游
2、ac和核心的互联vlan和ap的管理vlan是同一个广播域,可以不用配option 43
3、直接转发模式,ac上可以不起业务vlan,ac和核心交换机上可以只放行一个互联vlan 10
4、ac上要启两个vap魔板,两个ap-group,每个ap-group对应一个vap魔板
5、2个vap和ap-group魔板可以调用 相同的一个ssid和security魔板
6、漫游注意ssid和密码都得一样

直接转发模式配置:

ap-id 1 type-id 69 ap-mac 00e0-fc0a-43b0 //第2个ap
ap-name 2-lay-01
ap-group test101

现在漫游后的数据转发流程是:

sta->漫游后的ap->sw->Hac->家乡Hap->sw->外网

如果是隧道转发数据流程是:

sta->漫游后的ap->sw->Hac->sw->外网

没有次优路径绕行

如果非要用直接转发模式,为了解决hap家乡代理,数据有次优路径绕行,可以配置ac做为家乡代理,不用再把数据回到家乡hap上面再出去,而是到ac后直接发给核心交换机出去上网

vap-profile name test100 //第一个ap的vap魔板
home-agent ac

vap-profile name test101 //第2个ap的vap魔板
home-agent ac

只要AP获取到地址就能查看到mac
