(TRY)

进展：

section 3 ipv6组播 做完，比较简单。

section 4 高级特性，进行中

问题注：

1）这一部分的验证需要搭建一些外部环境，并将设备桥接到网卡，

2）具体需要搭建的外部环境是：

桥接虚拟网络到网卡

radius server，

tacacs+ server

3）4。2部分没有外部环境敲入会导致链路down，可以暂时跳过。

4）搭建桥接并不难，只是需要一些时间测试验证。搭建外部服务器软件，没有可供参考的验证过的详细步骤之前可能 需要更多的测试时间，没有时间和条件的话可以先掠过，平时工作中留意这方面。

明日计划：

v1基本做完。周五做备份保证周六前全部做完。

周末回头仔细验证v1以及手边其他事情
