two topic with same name in connected routers sometime, message does not replicate to each other My question is: what correctly config for same topic name: 1. create one topic in one router only, the other routers does not need create a topic with same name. 2. create same topic on each router. Does it legal, because topic is global, two topics with same name. we used No.2 configure. sometime, one router does not get message. Is this configation correct? BTW we have 10 routers connected each other with unlimted Router. Thank you ! Ping Lu    More>>

My question is: what correctly config for same topic name:


1. create one topic in one router only, the other routers

does not need create a topic with same name.


2. create same topic on each router. Does it legal,

because topic is global, two topics with same name.


we used No.2 configure.


sometime, one router does not get message. Is this configation correct?


BTW we have 10 routers connected each other with unlimted Router.


Thank you !

You can use both ways. If a message arrives at a router and the topic isn't defined, it is created internally. However, if you want to subscribe to a topic, it must be in JNDI which in turn requires to define it.


Look here how subscription exchange works in a router federation. If a router don't get a message for a particular topic then this might be a problem in timing (e.g. the router which sends the message didn't receive the remote subscription yet).
