In an 11g grid infrastructure home, when trying to have two or more listeners, each on separate interface, it can be observed that the listener on the virtual interface will have an additional endpoint on the physical interface ip.
For example, we need to have LISTENER1 to listen on 10.1.0.1:1521 (public ip) and LISTENER2 on 10.1.0.2:1522 (virtual ip). The LISTENER2 will automatically have two endpoints, 10.1.0.2:1522 and 10.1.0.1:1522.
Setting DYNAMIC_REGISTRATION_<listener name> = off can avoid this behaviour. But this can lead to listener having status INTERMEDIATE / Not All Endpoints Registered in crs_stat. This is because setting the parameter to off will cause the grid agent not being able to register with the listener.
