Ports from the same device are not connected (this validation is done in the physical layer).
Verification Technique:
6.1.12 Pseudowire
The Pseudowire topology represents a bi-directional link between the endpoints of an MPLS-based
pseudowire tunnel in the network. In the VNE model, the endpoints of the link are PTP Layer 2 MPLS
tunnel IMOs (IPTPLayer2MplsTunnel), which represent the pseudowire tunnel endpoints.
pseudowire tunnel in the network. In the VNE model, the endpoints of the link are PTP Layer 2 MPLS
tunnel IMOs (IPTPLayer2MplsTunnel), which represent the pseudowire tunnel endpoints.
Prime Network discovers PWE3 Network layer topology by searching for matches between the local and
remote router IP addresses in any one-hop-away remote side’s PTP Layer 2 MPLS tunnel. In particular, it
compares the local and remote router IP addresses and tunnel identifications.

compares the local and remote router IP addresses and tunnel identifications.
Link type: Tunnel
Discovery and verification technique:
6.1.13 GRE Tunnel
The GRE Tunnel topology represents a link between the endpoints of a GRE tunnel in the network. In the
VNE model, the endpoints of the link are GRE Tunnel IMOs (Generic Routing Encapsulation (GRE) Tunnel
Interface (ITunnelGRE)), which represent the GRE tunnel endpoints.

Interface (ITunnelGRE)), which represent the GRE tunnel endpoints.
Prime Network discovers the GRE topology by comparing the source and destination IP address on both
sides accordingly.
sides accordingly.
Link type: GRE tunnel
Discovery and verification technique:
6.1.14 VPN
The VPN topology represents a link between two VRFs that are part of a VPN. In other words, VPN traffic
can pass between customer sites connected to these VRFs. In the VNE model, the endpoints of the link
are VRF IMOs (Virtual Routing Forwarding (VRF) Entity (IVrf)), which represent the VRF forwarding
entities in the network element.

entities in the network element.
Prime Network discovers MPLS-BGP-based VPN network topology by searching for the existence of a
local VRF entity’s imported route taget among the exported route targets of any remote side.
