### Pre-check - [X] I am sure that all the content I provide is in English. ### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version dubbo java 3.3.1 ### Steps to reproduce this issue <dubbo:application name="${application.name}"/> <dubbo:registry protocol="zookeeper" address="${dubbo.address}" /> <dubbo:protocol name="dubbo" port="${dubbo.port}" ext-protocol="tri" preferred-protocol="tri"/> I'd like the provider to be able to support both the dubbo and triple protocol with a port. When export the triple service it not found triple protocol. And use tri.default to look for extension. If I add triple protocol config. It seems one provider export triple protocol twice which not allowed. <dubbo:protocol name="tri"/> ### What you expected to happen How to use ext-protocol and preferred-protocol to smoothly change the dubbo protocol to the triple protocol <dubbo:protocol name="dubbo" port="${dubbo.port}" ext-protocol="tri" preferred-protocol="tri"/> ### Anything else _No response_ ### Are you willing to submit a pull request to fix on your own? - [X] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
