[问题求助] juniper路由器的组播问题！！

描述：组播实验拓扑图
图片：


近来碰到一个关于实现组播的问题，一时没法解决，请有相关经验的高手提供解决办法：  
实际网络描述：组播源------->思科交换机3750--->JUNIPER M40路由器------>juniper M20-------->思科7609交换机，这种只要在思科3750和7609之间起TUNNEL就可以将组播源透传到7609上，这样可以实现 H
但另一种实际网络如下：组播源------->思科交换机3750--->JUNIPER M40路由器------>juniper M20-------->JUNIPER M40-1，这种方式下也想实现CISCO3750和M40-1之间的透传，但不能实现！！！

关于第二个实际网络烦请高手提供建议！！JUNIEPR路由器上有TS卡的！！我用实验模拟了以上第二种实际网络：组播源------->思科路由器3640--->JUNIPER M7i-1路由器------>juniper M7i-2-------->用户端，在这个实验中，我想把CISCO3640和M7i-2之间起tunnel，并且M7i-2启用PIM DM模式，这样想组播源发组播包透传到M7i的硬件是：[email=yhuser@M7i-1]yhuser@M7i-1[/email]> show chassis fpc pic-statusSlot 0 Online E-FPC oI6XPIC 0 Online 1x G/E SFP, 1000 BASE 94mTIPIC 1 Online 1x G/E SFP, 1000 BASE
