Converting broadcast to multicast

[m.athif]

Hi,

We are using a application which generates broadcast traffic on 192.168.1.255 with UDP port 5555 which goes to the router and from there to a satellite switch. THe problem is the satellite switch does not take broadcast traffic but can accept multicast traffic.

How do we convert the broadcast traffic to multicast in the router.?

You would have to use the interface command

ip multicast helper-map broadcast multicast-address 5555 extended-ACL-number

Here's the URL on the cisco website http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/fiprmc_r/mult/1rfmult2.htm#1089140

Thanks for the help.

The ip multicast helper-map command converts between broadcasts and multicasts. You can specify the addresses to use for the conversion and also restrict it with an access-list.
