communicate two IS using Broker?

I want to make communicate two IS using Broker.
For that I configured IS-1 broker woth the address of IS-2. Now from IS-1 I publish one document. But its not hitting the trigger at secong IS. And How to give that document I/P in Subsciber service as well as in trigger.
Can any one help.

Make sure you broker setting on both ISs are same including “Client Prefix” and “Client Group”, you are not publishing the document locally and the document you are publishing is synchronize with the Broker.

One more think, make sure the document which you are publishing and trying to subscribe on the other IS is exactly at the same location on both servers. You can always create a package for common documents on both servers where you can keep those document which will be subscribed by other ISs and keep that package sync.
