6.1.3 BGP
The BGP topology represents a TCP connection between two BGP entities that facilitate the “BGP
neighborhood” in the network. In the VNE model, the endpoints of the link are the MPBgp IMOs (Multi-
Protocol BGP Entity (IMPBgp)), which represent the BGP service running on the router.

6.1.4 Business
The Business topology does not represent any specific link or relationship in the network. It can
represent the relationship between any two objects in the model, which can be business objects or
network objects. These links are created in the Prime Network gateway.

6.1.5 Ethernet
The Ethernet topology represents a link between two Ethernet ports that are connected in the network.
In the VNE model, the endpoints of the link are Ethernet IMOs (Ethernet Interface (IEthernet)), which
represent the Ethernet ports.

Prime Network conducts a discovery of the Ethernet data link layer topology by using various types of
data. This includes information from, for example, OAM, CDP, LLDP, STP, and can include MAC learning
information. All types of data are collected and, based on priority, used to verify the adjacency between
two ports.
Certain data that is used for discovery might be device specific. For example, Inter Chassis Link and Inter
Rack Link information that is available only for specific device type.

Note: Many service providers use L2PT to configure customer access to VLAN ports. This avoids
the need to process Layer 2 protocols such as CDP. In these scenarios, discovery may
create links between ports that are not directly connected, because the Layer 2 protocol
information is tunneled and does not reflect the actual physical links. This problem can be
overcome by configuring static links on these ports. These static links will override any
incorrect dynamically discovered links.
