L2VPN discovery
process
During the L2VPN discovery process, the
MPLS Topology Server
creates within its repository a data model representation
of the discovered L2VPN topology. The LDP-signaled L2VPN data model is shown in
LDP-signaled L2VPN data model, and the BGP-signaled L2VPN
data model is shown in
BGP-signaled L2VPN data model.
The VLAN modeling for Ethernet-VLAN VPWS and VPLS is shown in
VLAN modeling in the L2VPN data model.

the L2VPN data model

Typically, every relationship has an inverse relationship. For
example, the relationship “Underlying” is the inverse relationship of
“LayeredOver.”

Forwarder, ForwarderEndpoint, PseudoWire, VRF, RouteTarget, VPN, and VLAN
classes. More detailed descriptions of these classes are available in the

The discovery and modeling of the LdpProtocolEndpoint and LdpAdjacency
objects is specific to LDP-signaled L2VPNs. The discovery and modeling of the
VRF and RouteTarget objects is specific to BGP-signaled L2VPNs.
