CCNP-第十七篇-VXLAN(三)
今天主要有点点复习的效果,这篇内容会偏少一点点
 今天主要演示VXLAN环境下的跨子网的vxlan
跨子网的VXLAN
部署方式
 1.集中式GW部署,意味着内网里面就一个大网关 ==本次演示
 2.分布式GW部署,这里面会涉及到MPLS+BGP,不过很多IDC都用这种.

建立VTEP的过程后面这里这个protocol,适用于分布式的,可以看到后面直接只能跟着bgp了
本章VS上章
1.上一章的环境是相同VNI以及左右的PC是同网段的情况下
2.这一章的环境乃是不同VNI+不同BD(其实无所谓,反正只能本地有效)+不同网段
3.本次同样会把dis  current-configuration 公布以及注解
那么,就展开PK啦
网络环境
 
网络环境如图所示
最终需求:左右PC互通
开始配置
1.首先底层都配置起来先,这个就不截图了,一会dis-cu自己看
 2.ce12800设备有点问题,他接口改三层不能互联,要用vlan做才能互通
 2.开始配置VLXLAN
CE2
 
 
 如果觉得眼花缭乱的可以去下面直接看dis cu 我这个只是配置过程
CE3
看到这会有人说跟上一篇不是一样吗,不就换了个源和目的地,这么简单?
VXLAN确实不难,但是没这么简单,切往下看
上一篇的环境是同网段,但是这一章是不同的vni不同的网段
采用集中式网关,所以这里需要把nve隧道指向中间CORE,而不是对端,一会会解释.
做bd和vni的时候尽量用100以内的,100以外有点问题的.我这里全改了,但是拓扑图没改
直接贴配置然后再解释了,

下面的就是接口做trunk
然后下面做对应的vlan就行了
电脑ip为.10
gw为.1两边互通
