乾頤堂安德華為DC實(shí)現(xiàn)指南新書(shū)一瞥-VXLAN的靜態(tài)部署-基礎(chǔ)VXLAN實(shí)驗(yàn)案例
乾頤堂網(wǎng)絡(luò)實(shí)驗(yàn)室-安德（周亞軍）
VXLAN（Virtual eXtensible Local Area Network）采用MAC in UDP（User Datagram Protocol）封裝方式，一種網(wǎng)絡(luò)虛擬化技術(shù)。已經(jīng)變成當(dāng)下SDN以及大2層的業(yè)界標(biāo)準(zhǔn)，當(dāng)然也是不折不扣的網(wǎng)紅技術(shù)。是當(dāng)下華為數(shù)據(jù)中心的當(dāng)紅炸子雞，明年初的DATACOM HCIE也需要對(duì)應(yīng)知識(shí)。
一【實(shí)驗(yàn)?zāi)康摹?/p>
通過(guò)部署VXLAN基礎(chǔ)實(shí)驗(yàn)了解VXLAN的工作原理
了解VXLAN的業(yè)務(wù)接入方式和數(shù)據(jù)轉(zhuǎn)發(fā)
二【實(shí)驗(yàn)環(huán)境】
本實(shí)驗(yàn)采用ENSP完成部署，其中Leaf設(shè)備和SPINE設(shè)備采用ENSP中CE設(shè)備，下聯(lián)的傳統(tǒng)接入網(wǎng)絡(luò)采用ENSP中的5700設(shè)備。
CE設(shè)備的底層IGP采用OSPF即部署Underlay網(wǎng)絡(luò)。
三【實(shí)驗(yàn)原理】
此處省略，請(qǐng)參考正式書(shū)籍
四【實(shí)驗(yàn)步驟】
1）完成底層的IGP（Underlay網(wǎng)絡(luò)），為后續(xù)部署其他協(xié)議做前置準(zhǔn)備

配置完畢OSPF來(lái)驗(yàn)證鄰居以及路由情況：

Leaf1和Leaf2作為業(yè)務(wù)接入點(diǎn)，連接了傳統(tǒng)接入交換機(jī)5700，流量需要經(jīng)由Leaf設(shè)備的2層子接口進(jìn)入VXLAN，之后完成大2層互訪。在本步驟中采用了相同的橋接域（brideg-domain）10，后續(xù)實(shí)驗(yàn)為了理解這個(gè)概念，我們會(huì)采用不同的橋接域。

為了完成完整的數(shù)據(jù)通信，我們來(lái)配置當(dāng)下情況的傳統(tǒng)接入網(wǎng)絡(luò)。
在SW1和SW2（5700）配置VLAN

在終端PC上完成數(shù)據(jù)測(cè)試，PC1可以和PC2完成通信。
可以在SPINE設(shè)備上完成抓包，來(lái)觀察流量，當(dāng)然您只能看到隧道封裝，而無(wú)法看到172.16.1.0網(wǎng)絡(luò)的流量。如下所示
接下來(lái)我們來(lái)查看Leaf1和Leaf2的MAC地址表，這一點(diǎn)很關(guān)鍵，因?yàn)閂XLAN是大2層網(wǎng)絡(luò)，所以需要觀察同一子網(wǎng)下的2層轉(zhuǎn)發(fā)表。

其通信示意圖如下所示
從業(yè)務(wù)終端172.16.1.1到172.16.1.2的流量，經(jīng)過(guò)傳統(tǒng)接入網(wǎng)絡(luò)，攜帶TAG10的幀從Leaf1的2層子接口允許進(jìn)入VXLAN隧道后，此時(shí)剝離掉所有TAG，轉(zhuǎn)發(fā)到VXLAN隧道內(nèi)，即VNI10，VXLAN隧道在Leaf1和Leaf2之間部署，此時(shí)沒(méi)有攜帶任何TAG的幀到達(dá)Leaf2，Leaf2會(huì)剝離VXLAN封裝準(zhǔn)備從2層子接口發(fā)送。注意此時(shí)會(huì)增加2層子接口下配置的DOT1Q封裝的VLAN ID（10），發(fā)送到傳統(tǒng)接入交換機(jī)。
5）
為了理解橋接域，我們來(lái)修改步驟2中的配置，本步驟在不同的Leaf設(shè)備上配置不同的Bridge-domain。VNI能標(biāo)識(shí)VXLAN網(wǎng)絡(luò)中的2層域，而B(niǎo)ridge-Domain是VXLAN網(wǎng)絡(luò)的實(shí)體，只具有本地意義，所以在此步驟中，我們修改Leaf2的橋接域，但VNI不做改變，依舊為20
[Leaf2]bridge-domain 20
//創(chuàng)建新的橋接域20
[Leaf2-bd20]vxlan vni 10
//試圖把橋接域20和VNI10綁定，但此時(shí)出現(xiàn)報(bào)錯(cuò)，該錯(cuò)誤表明，VNI10已經(jīng)和橋接域10完成了綁定，而橋接域和VNI是1:1的綁定關(guān)系。
Error: The VNI has already been bound to another bridge-domain.
解決方案：
bridge-domain 10
[Leaf2-bd10]undo vxlan vni 10 //在橋接域10下，解除VNI10和橋接域10的綁定關(guān)系
！
重新完成綁定：
bridge-domain 20?
[Leaf2-bd20] vxlan vni 10?
Info: Please disable dynamic ARP learning when the controller is used to deliver ARP entries.
除此之外，橋接域20還要和業(yè)務(wù)2層子接口進(jìn)行綁定，如下所示
[Leaf2]int g1/0/2.1 mode l2?
[Leaf2-GE1/0/2.1]dis th
