When planning the Avaya Session Border Controller for an Enterprise (ASBCE) deployment, a good practice to adopt is to name interfaces consistently, for example, Al as “Internal” or “Private” for connectivity to the Call Server. The ASBCE server has four network ports that can be configured as logical interfaces with different IP addresses, subnet masks, gateways, and VLAN IDs. The logical interfaces are named Al, A2, Bl, and B2. A good practice is to use a consistent naming convention for the interfaces that reflects their purpose and function. For example, you can name Al as “Internal” or “Private” because it connects the ASBCE server to the internal network and the Call Server. Similarly, you can name Bl as “External” or “Public” because it connects the ASBCE server to the external network and the Internet. This naming convention can help you avoid confusion and errors when configuring the interfaces and assigning them to zones.
