IGMP Proxy
|
|
==========
|
|
|
|
Internet Group Management Protocol (IGMP)
|
|
|
|
A IGMP Proxy to send IGMP host messages on behalf of a connected client.
|
|
The configuration must define one upstream interface, and one or more downstream interfaces.
|
|
If multicast traffic originates outside the upstream subnet, the "alt-subnet" option can be used in order to define legal multicast sources.
|
|
|
|
simple example:
|
|
---------------
|
|
|
|
Interface eth1 LAN is behind NAT. In order to subscribe 10.0.0.0/23 subnet multicast which is in eth0 WAN we need igmp-proxy.
|
|
|
|
.. code-block:: sh
|
|
|
|
# show protocols igmp-proxy
|
|
interface eth0 {
|
|
alt-subnet 10.0.0.0/23
|
|
role upstream
|
|
}
|
|
interface eth1 {
|
|
role downstream
|
|
} |
