Multicasting Issues
-
@kenneth.sisco said:
sounds like, to me, the switch is not allowing udp broadcast forwarding. This is just a guess at this point.
I’ve tested Multicast, and all seems to be working fine.
I’ve also messed a lot, today, with the fog scripts. Hopefully things are better and I’ve been republishing them as I find things and fix them too.
To me, like Wayne suggested, you should start by imaging within the same switch first (not across vlan’s).

I’ll reach out to our network team on Monday, then, and see if they’ll help me setup a test environment. Thanks for the help - I’ll report back soon!

@kenneth.sisco Make sure that your network switches have igmp forwarding or snooping enabled. If you have vlans in your network the igmp settings are typically set on a per vlan basis. The igmp settings allows the switch ports to subscribe to the multicast channel. The multicast stream will only be sent to ports and switches that subscribe to the multicast request. This keeps multicast traffic off switches where there are no subscribers.

So I worked with our network team and we were able to setup a small DHCP pool on the server VLAN temporarily for a test, and it worked fine. Once we tried again cross-VLAN, we had the same issues. I’ve copied the multicast.log section of the successful multicast below. The unsuccessful one is the same as my prior post in this thread. What I find interesting is that the multicast.log file shows that there is a new connection from the client cross-VLAN and even echoes its IP Address, but never transfers any data.
Successful multicast (same VLAN; shortened to allow for forum posting):

@kenneth.sisco making a connection is simple but the udp stream is not being allowed to pass after the initial connection is made. The separated network method you used sounds to have a slight difference from the real network side. I don’t know what or where. This does not sound like something fog is failing to do though, like I said, I’d take a look if you can on whether broadcast forwarding is on.
Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

I agree with Tom. Broadcast forwarding is exactly what you need. This happens on your router - as a routing device is the only way that data from one LAN (or V-LAN) can traverse to other LANs (or V-LANS).
Broadcast forwarding is called different things based on what vendor / piece of equipment you use. But it’s quite simply that which allows broadcast traffic to pass through a router. You’re network team don’t need to open everything up, they just need to allow passage from the server vlan to other vlans, and back. If your network team is really skilled, they can even limit it to a specific port on a specific switch, or a specific sending IP (the fog server’s IP).
-
So I’m working with our network team to troubleshoot this, and we have “broadcast forwarding” working for the most part, but we’re going to keep digging. One thing we were concerned about was TTL on the client side. We can see the TTL from the server in the multicast.log, but we’re concerned about what the TTL is on the udp-receiver command. Is there a way to see that? Or a way to specify it? I was looking for the task files that 0.32 used to have stored in the tftpboot folder, but this version of Fog handles that differently, so I’m not sure where to find them.

It’s set to 32.
The setting is part of the init, so to change it, you’ll need to edit it.
Here are instructions on editing the init:
https://wiki.fogproject.org/wiki/index.php?title=Modifying_the_Init_ImageHere’s the command I used to find the command and it’s output.

We’re still having trouble narrowing this down, but is it safe to assume that if Multicast is working across the same VLAN that it’s no longer a fog issue?

I would think so! Looked into igmp settings on your switches yet?
-
@Sebastian-Roth Yes, we’ve looked at IGMP, but our topology is fairly complex. Currently the network team is working on moving rendezvous points closer to the server/clients and investigating potential issues in NXOS, as we recently migrated from Cisco IOS cores to Nexus.
Unfortunately, my visibility on this is very limited, so I’m doing my best to keep this rolling on the server side as we troubleshoot.
I’ll update with more info later as we progress.

Cool - issue resolved!
This was absolutely an issue on our network, but we’re not sure if it was an old static Rendezvous Point that was configured on our core or if it was our VPC redundancy between our two nexus switches, but we were able to solve it by disabling pim on one of the nexuses and removing that static RP.
Thanks for the help on investigating, everyone. It’s much appreciated.
