The proxy allows multicast routers to read and learn about membership information. Most of them do not require routing protocols, but some of them work in particular to topologies. The protocols are PIM-DM, DVMRP, and PIM-SM. The Proxy has a US and DS Interface. Using a proxy can benefit in increasing security, privacy, and performance.
It acts as an intermediary between the Internet and the client. It hides all the important information about the client. Turning off the proxy can help in simplifying the configuration of the network and, in some cases, enhance the performance too. So, it's up to you if you want to turn on or off the proxy.
This proxy enables multicast routers to read and learn membership information. Moreover, it forwards multicast packets as per the group membership information. It works in particular topologies and most of them are the ones that don't demand routing protocols. These protocols are PIM-SM, DVMRP, PIM-DM.
This proxy has a distinctive upstream and downstream interface. In the case of the downstream interface, the proxy works on the protocol on the router's side. If you talk about the upstream interface, then the proxy works on the protocol's host side.
The proxy has created a unique mechanism for multicast forwarding based on the membership information. Furthermore, the router is going to line out the forwarding packets. IGMP proxy makes forwarding entries and puts them in the multicast forwarding cache.
With no internet group protocol management proxy configuration, the multicast traffic will be treated as broadcast transmission. Moreover, the forward packets will be sent to each port on the network. With this proxy, the traffic is forwarded to the multicast group as per the information.
With a proxy, no additional traffic can be generated, which leads to a reduced traffic package using a switch. In such a scenario, it is recommended to keep the proxy turned on all the time. By doing so, the multicast traffic will change into unicast traffic. This will provide you better functionality and productivity of your router device.
You get a few benefits when you turn on IGMP proxy. These benefits include:
In case you are planning to stream on Netflix or any other platform, then you must keep IGMP proxy enabled. This will resolve mirroring issues as well. If you find that the benefits mentioned above are of no use to you, then you must disable the proxy. This is recommended because the router continues to monitor multicast transmissions and it will drain your device's processing power.
If you find that disabling the IGMP proxy is the right thing to do, then you must carry out the steps below.
