Question

翻译大神来~有分追加~

A stop filter will be set if a multicast packet is received prior to a "join" to an IP multicast group where the received multicast address belong if the "Multicast stop filter" option is enabled. This means that IP multicasting based on IGMP is required in order to get multicast through the network. Multicast filters will be properly set only for IP multicast packets if this option is disabled. That means that multicast packets not based on IP will be forwarded in the same way as broadcast packets. This is acceptable if the non IP based multicast network load is reasonable low.

Answer 1

A stop filter will be set if a multicast packet is received prior to a "join" to an IP multicast group
如果“多点传送阻止过滤器”选项处于启用状态，对于一个IP多点传送组来说，
where the received multicast address belong if the "Multicast stop filter" option is enabled.
如果接收一个多点传送信息包先于一个“接入”，而接收的多点传送地址又属于这个IP多点传送组，那么阻止过滤器将被设定。
This means that IP multicasting based on IGMP is required in order to get multicast through the network. 这意味着为了让多点传送通过网络，就需要基于IGMP的IP多点传送。
Multicast filters will be properly set only for IP multicast packets if this option is disabled.
如果此选项禁用，多点传送过滤器将被正确设定，仅用于IP多点传送信息包。
That means that multicast packets not based on IP will be forwarded in the same way as broadcast packets.
那意味着不基于IP的多点传送信息包会被与广播信息包相同的方式转寄。
This is acceptable if the non IP based multicast network load is reasonable low.

如果基于多点传送网络加载的非IP合理的降低是可接受的。

Answer 2

在多点传送包预先接受有多播地址的IP传送组接口，而且组织停播过滤器选项开启的话，阻滤波器就会启动。也就是说通过网络的多重广播需要基于IGMP的IP多重传送。只有在IP多播数据包选项关闭时组播过滤器才会正常启动。这意味着不基于IP的多播数据包会和广播报文以同样的方式发送。如果不以IP为基础的网络路载在合理的低值的话，这是可以接受的。

额。翻译的磕磕巴巴的。水平有限。
