Hi guys,
Is there anyone has experience about Chromecasts?
My client ask me that can we enable multicast for Chromecasts?
I read some other posts, but they have some problem with router, APs, IP firewall, even with HMOL...
I have no experience with this so any help is appreciated.
Thanks in advanced.

Can you restate your question in a different manner, please? Google's Chromecast should work just fine with our products, at least within my own experience. The Chromecast uses mDNS for advertising it's services, true, but once you begin "casting" to it you are doing unicasts. If the client devices you wish to talk to the Chromecast are on the same subnetwork then our access points should have no problms forwarding that traffic.

If you want clients in different VLANs or subnetworks (i.e. not in same broadcast domain) to connect to the Chromecast, then you need a helper to get the service advertisements forwarded from one broadcast domain to another.
   
Some simple testing I did indicates that our Bonjour Gateway supports them just fine once "*._googlecast._tcp." has been added to the configuration.

Hi Mike,
Thanks for your reply.
We are trying to create a wireless just for Chromecast in school.
So far we created a SSID with PSK, broadcasting 2.4GHz only.
Then we turn on Chromecast and connect it to wireless, it get the correct IP address but it not function as we are expected.
I wonder is there any thing that I should configure?
And do we have any resource about configure wireless for Chromecast?

Thanks Mike

Tung,
What does not function as expected? Have you looked at Google's Chromecast troubleshooter site https://support.google.com/chromecast/troubleshooter/2995236 ?

I had the same problem, i would put in the credentials for the AP and chromecast could not connect to the server... I turned on my old wifi and set up new SSID and it worked... I could not find anything on google to help. .. I then scoured through all the settings and then enabled IGMP ... it then worked for me.

My issue with the Chromecast is that it doesn't seem to like the firewall policy I have in place on the user profile. I'm assuming the explicit 'Deny' rule at the end of the statement is the primary cause of the problem. However I have never been able to get an answer regarding the exact protocols or ports etc. that need to be allowed in order for the Chromecast to function with a firewall in place.
