MPLS topology maps contain MPLS and VPN objects along with their relationships and connections. In a map display, a node is a graphical representation of a topology object, and an edge is a graphical representation of a relationship or connection between objects.

Default nodes and edges for MPLS topology maps identifies and describes the default nodes and edges that may appear in an MPLS topology map. In the Map Console, you can also select Map > Map Legend to see a similar list.

Icon / visual indicator

Description

Standard router icon with P inscription—represents the following:

  • A routing device that is operating as a Provider (P) router

  • An MPLS service object that is associated with the P instance

Standard router icon with PE inscription—represents the following:

  • A routing device that is operating as a Provider Edge (PE) router

  • An MPLS service object that is associated with the PE instance

Standard router icon with CE inscription—represents the following:

  • A routing device that is operating as a Customer Edge (CE) router

  • An MPLS service object that is associated with the CE instance

Standard router icon with MULTI_VRF_CE inscription—represents the following:

  • A routing device in an L3VPN that is operating as a multi-VRF CE router

  • An MPLS service object that is associated with the multi-VRF CE instance

Standard switch icon with P inscription—represents the following:

  • A switch that is operating as a P router

  • An MPLS service object that is associated with the P instance

Standard switch icon with PE inscription—represents the following:

  • A switch that is operating as a PE router

  • An MPLS service object that is associated with the PE instance

Standard switch icon with CE inscription—represents the following:

  • A switch that in an L2VPN is operating as a CE switch or a CE router

  • A switch that in an L3VPN is operating as a CE router

  • An MPLS service object that is associated with the CE instance

Standard switch icon with MULTI_VRF_CE inscription—represents the following:

  • A switch in an L3VPN that is operating as a multi-VRF CE router

  • An MPLS service object that is associated with the multi-VRF CE instance

Represents an L2VPN or L3VPN.

Represents a Forwarder in an L2VPN-related map.

Represents a VRF in an L3VPN-related map.

Solid line can represent a physical connection, a logical IP connection, a logical VLAN connection, a membership, or a group relationship.

Jagged line can represent any of the following:

  • A network connection between devices

  • A virtual link between a PE-VRF and a CE device

  • A virtual link between a PE-VRF and a CE-VRF

A PE-VRF is a VRF is that hosted by a PE device, and A CE-VRF is a VRF that is hosted by a multi-VRF CE device.

Directed solid line can represent a dependency.

In an LSP Hops map, represents an LSP in No Highlight LSP mode.

Directed dotted line can represent composition or an LSP in Highlight LSP mode. When representing an LSP in Highlight LSP mode on an LSP Hops map, the line animates to show the direction of packet flow through the LSP.
