Hi to everybody,
This is my issue:
I’ve got 2 multicast streaming encoders witch ports are 192.168.10.1 and gateway 192.168.24.1,multicast address 225.1.1.1/2:1234.
Then I’ve got to route it on 4 eiop tunnels to connect 1 receiver per feed cause there are 4 different site to connect.
All of this are on an intranet network and there are for example:
10.0.21.7
10.0.22.7
10.0.23.7
10.0.24.7
10.0.25.7
Now I’ve tried to route all with pim but the ether1 of “server” router multiply the bandwidth by 4,for example if the total streaming band would be 2 Mb I have 8 Mb on ether1 ,just like 2 Mb per tunnel.
Can you suggests me what could be the reason for that and/or witch could be the best configuration for this purpose?
Thank you in advance,i’know that my explanation it’s not very good,but this is a new world for me

This is “working as advertised” because an EoIP interface is one network path. If you had 4 receivers at one site, then you would only get one stream’s worth of bandwidth. EoIP is a tunnel, so even though all 4 tunnels go to the Internet, the Internet doesn’t participate in your multicast groups, so you can’t just send one copy and let the Internet split the traffic somewhere upstream.
Basically, you have 4 links, each of which has at least one active client, so each one must get a copy of the stream.
If you can cause the various tunnels to traverse different router interfaces, then you can spread the bandwidth out that way, but as far as the logical topology is concerned, each tunnel is its own path.
Hi ZeroByte,
Thank you for your quick reply, i was thinking that eiop could be the problem…anyway there could be a better way to do this?without the use of eiop?
EoIP isn’t causing the problem per-se - it’s the fact that you have 4 remote sites. If a copy of the packet is needed at 4 remote sites, then unfortunately, you have to send 4 copies. You’re not going to get across-the-internet multicast for this, which would be the only other way to send one copy into the Internet and let it come out at 4 different places.
If you’re really sure there’s something sub-optimal going on, then post a diagram of your router’s connections - physical interfaces with IP addresses and so forth.
My understanding is this:
LAN1 – ether1
----[router]—ether3 ---->Internet
LAN2 – ether2
And there are 4 remote sites, each with a single EoIP tunnel to the router’s public IP on ether3 (in this diagram)
