I have a USR/3Com Totalcontrol NAS with PRI/T1 cards in it. Does anyone know if these support multicast by default, and if not can someone point me the direction of some documentation on how to turn this on? Also I just setup another one of these boxes, but it wont let me telnet into it, is there something I need to turn on in order to be able to telnet into this box?

You'll need a HiPer ARC router card installed in the chassis to do multicast. The Netserver router card has no multicast capability. Multicast is disabled by default on the HiPer ARC. To turn it on you do something like: set ip multicast proxy interface eth:1 set ip igmp eth:1 multicast_forwarding enabled set network user default igmp multicast_forwarding enabled set network user default igmp multicast_proxy enabled set network user default igmp routing enabled This seems to work for users wishing to receive multicast via dialup.

if a user is configured via radius with no multicast radius options, but the ARC has the commands below configured, will that user be able to receive multicast? I can add the 5 lines to my ARC's, but don't want to have to add 3 lines to every users radius profile if I don't have too. At first look it doesn't appear to be working.

Yes - Its very easy. See the hiper arc uses a template, user for all its configuration. If radius provides the data, the template is overridden else the template is used. So all you have to do is setup the default user on the hiper arc local configuration with multicast options. That will apply to all your radius users when they dial in.

For multicast to work - you do need to have the multicast server (real or Ms) on the same wire of if its a hop away - you should have PIM dense mode enabled on all the router hops/interfaces. Also I think you have to set the multicast IGMP address on the Hiper arc. I think the command is set ip_source_address igmp <ip address of the interface> -V

You have to setup your network with PIM dense mode, sparse mode will not work. So your egde router should be set with pim dense mode. Once that is done you want to set this on the hiper arc set ip appLICATION_SOURCE_ADDRESS igMP <eth:1> or <eth:2> Which ever interface is attached to that network.

You can use Media player or real player - and the statistics will show that you are using multicast or unicast. If it uses unicast then there is a problem. Now technically you cannot go to www.mediacrossing.com unless and until your network is attached to the mbone. What you need to make sure is that your upstream provider has multicast turned on - on his routers so that you are capable of receiving multicast packets. If that is not there - you cannot do multicast. We had to contact our provider and ask them to enable multicast on their routers, once that is done, the ARC forwards the packets without any problems. Your edge router and all the core routers in the path should have PIM dense mode.

Sparce-mode will work but for most part has issues, thus use dense mode. If you have Ripv2 enabled on the ARC - you do have the multicast enabled - thus you will seee multicast packets - however to make it work in our network I had to configure the default user and the ethernet interface for igmp.

we have multicast on our network, and thru our providers, that part is all working. Whats wierd, is I dialed into an ARC that I did not enable multicast on, and still got "multicast" in media player to mediacrossing.com..........this is accross my sparse-mode network!
Sparce-mode will work but for most part has issues, thus use dense mode. If you have Ripv2 enabled on the ARC - you do have the multicast enabled - thus you will seee multicast packets - however to make it work in our network I had to configure the default user and the ethernet interface for igmp.
it says in the manual that if you don't configure the "application_source_interface", it just uses the ethernet interface anyways........so it appears thats not necessary
We had to contact our provider and ask them to enable multicast on their routers, once that is done, the ARC forwards the packets without any problems. Your edge router and all the core routers in the path should have PIM dense mode.
Do you have a test to see if it is all done right?
The easy way to test it - Have a realstreamer on the other side of your edge router, and try to attach to it or vice versa.
We have a realvideo server. So your saying I should just try to get a stream and if it *can* use multicast then realplayer will try that first and show it is using multicast?

when you say "multicast igmp address" what address is that exactly? Is that to point at my border router? Or is that a unique address to assign the arc?..........sorry i am a bit confused.

For multicast to work - you do need to have the multicast server (real or Ms) on the same wire of if its a hop away - you should have PIM dense mode enabled on all the router hops/interfaces. Also I think you have to set the multicast IGMP address on the Hiper arc. I think the command is set ip_source_address igmp <ip address of the interface>
I do see the multicast queries from the arc coming into my dialup lan: [root@bl0wfish mtrace-5.2]# /usr/sbin/tcpdump ip multicast Kernel filter, protocol ALL, datagram packet socket tcpdump: listening on all devices 21:21:42.561027 eth0 M usr2ts2.shreve.net > ALL-SYSTEMS.MCAST.NET: igmp query [ttl 1] 21:23:47.597577 eth0 M usr2ts2.shreve.net > ALL-SYSTEMS.MCAST.NET: igmp query [ttl 1] but I am unsure if its going out from my lan to the arc.........or getting thru the arc rather.
