请教下在必需使用自备普通路由的的情况下，又要用IPTV的连接方法

这个问题也困扰着我，希望大家一起研究推进。另外请楼主把标题加上上海字样。

openwrt可以起vlan51,85，但不知如何把eth0和eth1的其中一个口划到同一vlan中

我把RG200E上的ip link dump下来供你参考：
eth0.2应该是wan口，然后eth0.3~6是4个LAN口，itv口就是eth0.4

在DDWRT中的问题也是没办法识别eth0上其中某一个口。而RG200E官方firmware可以用eth0.2来对应wan口。

tangsoft · 发表于 2011-1-31 20:14:59

快绝望了：
RG200E-AB 的switch chip是BCM53101，支持4096个VLAN ID：
• Virtual Local-Area Network (VLAN)
• 4K-entry port-based and 802.1Q VLAN (full 4K range)
• VLAN based rate limiting
而WRT160Nv3,使用的是BCM5325E，只支持16个VLAN ID：
• Port-based and 802.1Q-based VLAN with 16 entries

估计很难模拟出一样的配置了。虽然还不确定这个vlan id是否关键。

肯定是可以模拟出一样的配置地，虽然我不会

PS：电信送的中兴H618C 用的也是BCM5325E交换芯片，配置界面和贝尔RG200E差不多，也支持IPTV

暂时没有头绪了。又回到研究RG200E-AB的官方配置，仍然不清楚itv口的具体配置。

tangsoft · 发表于 2011-1-31 22:20:56

就借宝地一用了，为了更进一步弄清这个RG200E－AB的工作原理，我把iptv机顶盒接在iTV口，然后在RG200E的WAN口接一台带tcpdump的上网本：tcpdump -vvv -XX -l -e -i eth1

采集到3种包：无vlan tag的pppoe(这个应该是宽带上网的pppoe拨号), vlan tag为46的DHCP请求（无vendor option，应该是那个所谓的管理端口），vlan tag为85的DHCP请求(有vender option，应该是iptv盒子发出来的，好些格式出了vlan tag其它和我昨天直接在iptv eth口采集到的一样）

根据最新的sniffer结果，基本上可以肯定RG200E对itv口的数据只是转发到wan口出去，并加vlan 85 tag，当然后面的igmp直播要另外处理。
但是wrt160Nv3上的dd-wrt对802.11Q的vlan支持实在是够呛。如果有人感兴趣，希望一起研究，多提供线索。
