Broadcast control

Hello,

My company is developing a product that relies on UDP broadcasts for client-to-server and server-to-client communications.

I believe I have solved the problem where a router is involved using the ip forward-protocol udp and ip helper-address commands.

My question is how this can be handled with a large switch divided into VLANs. Is there any way/command within the VLAN configurations to let a udp broadcast go from 1 VLAN to all the VLANs at the same time?

If not, does anyone have another suggestion as to how to do this?

Thanks,

Brian

Re: Broadcast control

Hi,

AFAIK, the only way is to involve a router with multiple ip helper-address commands.

Re: Broadcast control

I think so too. I was just checking.

Does anyone know if Cisco has some sort of a router-on-a-stick that could be stuck into a larger switch for such purposes?

Thanks,

Re: Broadcast control

The ip helper-address and ip forward-protocol udp commands work under vlan interface.

We have a DHCP Server which resides on vlan 1 which can be accessed by users in other vlans.We have configured DHCP ip helper-address on all vlans.
