A switch virtual interface (SVI) represents a logical layer-3 interface on a switch. VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need to communicate with hosts in another VLAN, the traffic must be routed between them. This is known as inter-VLAN routing.

A map of central Mexicali, Baja California, showing postal code allocations. Postal codes in Mexico are issued by Correos de México, the national postal service. They are of five digits and modelled on the United States Postal Service's ZIP Code system. The first two digits identify a federal entity (or part thereof). [1]
Before an address can be certified as deliverable (CASS-certified), it must first be standardized. Standardization converts an address into a standard format by correcting the address, if possible, and adding missing information, such as a ZIP code, to produce a complete address containing a street address, city, state, and ZIP code.
An organizationally unique identifier (OUI) is a 24-bit number that uniquely identifies a vendor, manufacturer, or other organization..

In the Cisco IOS, [1] they are used in several places, for example: To indicate the size of a network or subnet for some routing protocols, such as OSPF. To indicate what IP addresses should be permitted or denied in access control lists ...
IBGP uses extended community attributes in a common routing table to differentiate the customers' routes with overlapping IP addresses. IP VPN is most commonly deployed across an MPLS backbone as the inherent labeling of packets in MPLS lends itself to the identification of the customer VRF.
