Explanation:
http://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c07-732033.html
Border Leaves
The border leaves are ACI leaves that provide layer 3 connections to outside networks. Any ACI leaf can be a border leaf. These can also simply be called leaf switches. There is no limitation in the number of leaf switches that can be used as border leaves. The border leaf can also be used to connect to compute, IP storage, and service appliances. In large-scale design scenarios it may be preferred to have border leaf switches separated from the leaves that connect to compute and service appliances for scalability reasons.
Three different types of interfaces are supported on a border leaf switches to connect to an external router:
● Layer 3 interface
● Sub-interface with 802.1Q tagging – With sub-interface, the same physical interface can be used to provide a layer 2 outside connection for multiple private networks
● Switched Virtual Interface (SVI) – With an SVI interface, the same physical interface that supports layer 2 and layer 3 and the same physical interface can be used for a layer 2 outside connection as well as a layer 3 outside connection
