Additional Information

Ingress LSP

Information about LSPs on the inbound router. Each session has one line of output.

 

Egress LSP

Information about the LSPs on the outbound router. Each session has one line of output.

MPLS learns this information by querying RSVP, which holds all the transit and outbound session information.

Transit LSP

Number of LSPs on the transit routers and the state of these paths.

MPLS learns this information by querying RSVP, which holds all the transit and outbound session information.

To

Destination (outbound router) of the session.

 

From

Source (inbound router) of the session.

 

State

State of the path. It can be Up, Down, or AdminDn.

AdminDn indicates that the LSP is being taken down gracefully.

Rt

Number of active routes (prefixes) installed in the routing table.

For inbound RSVP sessions, the routing table is the primary IPv4 table (inet.0). For transit and outbound RSVP sessions, the routing table is the primary MPLS table (mpls.0).

Active Path

Name of the active path: Primary or Secondary.

This field is used for inbound LSPs only.

P

An asterisk (*) in this column indicates that the LSP is a primary path.

This field is used for inbound LSPs only.

LSPname

Configured name of the LSP.

 

Style

RSVP reservation style. This field consists of two parts. The first is the number of active reservations. The second is the reservation style, which can be FF (fixed filter), SE (shared explicit), or WF (wildcard filter).

This field is used for outbound and transit LSPs only.

Labelin

Incoming label for this LSP.

 

Labelout

Outgoing label for this LSP.

 

Total

Total number of LSPs displayed for the particular type—ingress (inbound), egress (outbound), or transit.
