vBNG on XRv 9000

2022-05-27 | No comments

最近抽空在EVE上配置测试了下Cisco BNG，把IPoE和PPPoE的功能验证下，记录下来，后续如果遇到排查BNG故障的问题可以借助模拟器验证一些命令和配置之类的。

XRv9K: xrv9k-fullk9-x-6.6.3
- vBNG好像不支持在xrv的镜像上运行，不支持RP base的session,所以这里用XRv9K这个镜像。
CSR 1000v: csr1000vng-universalk9.17.03.02-serial
- CRS 1000v 用来当DHCP server/DHCP Client/PPPoE Client, 版本没什么特殊的要求。
Freeradius
- 这里我桥接一个网卡到我的一个linux主机上，上面用docker起了一个freeradius。有关Freeradius相关的配置过程可以参考我的另一篇文章，Configure ASR9K AAA with Freeradius

最近有在考DevNet的认证，所以Mark一下如何去查认证考试代码。

参考一下思科certification的介绍页面， Associate -> NA, Professional -> NP, Expert -> Expert.

主要记录下DevNet各个考试的代码，以便后续查找.

	Name	Price
200-901 DEVASC	DevNet Associate Exam v1.0	300$

Professinal 对应的是NP, 需要2门考试才为NP; 两门考试一门为Core Exam, 一门Concentration Exam; Concentation Exam 有多个方向，选择一个方向的考试考过即可。

	Name	Price
350-901 DEVCOR	Developing Applications using Cisco Core Platforms & APIs	400$

	Name	Price
300-435 ENAUTO	Automating and Programming Cisco Enterprise Solutions v1.0	300$

需要先行通过350-901 Core Examp, 然后需要通过8h Lab Exam才可获得。
