What is the multi-layer map?
Multi-layer map
The multi-layer map is a display option on the Service Troubleshooting map. It allows you to view services through a series of separate network layers.
Note: The MPLS, IGP, and Physical layers are sourced through either CPAM/CPAA or VSR/NRC (NRC-P), which must be configured in NSP in order for the map to display services on managed NEs.
Troubleshooting workflow
Use the following Multi-layer Map features to troubleshoot map objects:

Tunnel support
The table below lists the different supported tunnel types in which an LSP path can be determined based on the IGP topology source (CPAM or VSR-NRC) to populate the IGP layer in the multi-layer map.

SDP |
GRE |
CPAM/CPAA runs SPF protocol to get actual path of LSP recorded in NFM-P. Both endpoints need to be in the same admin domain. VSR-NRC runs NRC-P path calculation. Endpoints do not need to be in the same admin domain. |
|
MPLS – LDP |
CPAM/CPAA runs SPF protocol to get actual path of LSP recorded in NFM-P. Both endpoints need to be in the same admin domain. VSR-NRC runs NRC-P path calculation. Endpoints do not need to be in the same admin domain. | |
|
MPLS – LSP |
CPAM/CPAA runs SPF protocol to get actual path of LSP recorded in NFM-P. Both endpoints need to be in the same admin domain. VSR-NRC returns PCEP related path discovered by NRC-P. If no PCEP related path is available, NRC-P runs path calculation to determine path. Endpoints do not need to be in the same admin domain. | |
|
MPLS – SR-TE-LSP |
VSR-NRC returns PCEP related path discovered by NRC-P. If no PCEP related path is available, NRC-P runs path calculation to determine path. Endpoints do not need to be in the same admin domain. | |
|
MPLS – SR-ISIS |
VSR-NRC runs NRC-P path calculation. Endpoints do not need to be in the same admin domain. | |
|
MPLS – SR-OSPF |
VSR-NRC runs NRC-P path calculation. Endpoints do not need to be in the same admin domain. | |
|
RSVP/TE (PCE) |
CPAM/CPAA runs SPF protocol to get actual path of LSP recorded in NFM-P. Both endpoints need to be in the same admin domain. VSR-NRC returns PCEP related path discovered by NRC-P. If no PCEP related path is available, NRC-P runs path calculation to determine path. Endpoints do not need to be in the same admin domain. | |
