Routing To Diff Instance Of SQL Server On Same Server

Remus,

thank you for your reply on (microsoft.public.sqlserver.notificationsvcs).

one more question :

Server_2 == Server_3

so I set up a route for db2:

CREATE ROUTE [rem_s2_route] AUTHORIZATION [dbo] WITH SERVICE_NAME = N'rem_s2' , ADDRESS = N'TCP://192.168.0.2:4022'

to create route for db3 (sql express) I tried

CREATE ROUTE [rem_s3_route] AUTHORIZATION [dbo] WITH SERVICE_NAME = N'rem_s3' , ADDRESS = N'TCP://192.168.0.2sqlexpress:4022'

this failed, what am I doing wrong or did I lost the plot? How do I diff beteen more than one instance of sql server on the same server? And can the port be the same on each instance of SQL Server?

thank you in advance
