Inter-site route
In this example, there are two sites. The first one, named site1, has an inbound thread conn_1, routing to an inter-site destination. This is another thread also named conn_1, but in a site named site2.
The inbound thread conn_1 receives a message 0.0.1 from the inbound protocol. It routes to an inter-site destination, which results in the message ID changing to 0.0.2.
In the second site, there is a single outbound thread conn_1 which is the destination pointed to by dest_1 in the first site.
The message it receives through the inter-site route has a message ID of 0.1.1 and a source message ID of 0.0.2. This is the message ID of the message in site1 that was routed here.
0.1.1 is sent through the outbound protocol.
