show mpls lsp abstract-computation
<brief | detail | extensive>;
<logical-system (all | logical-system-name)>;
<name lsp-name>;

Description

Display the ingress to egress abstract hop computation used by the constrained shortest path in the preprocessing for LSPs. The command output displays the various computation passes involved per LSP, and the qualifying exit devices for each pass. It also displays the affinity per pass, and the current start device chosen for the pass.

Options

brief \| detail \| extensive	(Optional) Display the desired level of output.
logical-system (all \| `logical-system-name`)	(Optional) Display the abstract computation for abstract hop constraints on all logical systems or on a particular logical system.
`lsp-name`	(Optional) Name of the LSP for which the abstract hop computation is displayed.

Required Privilege Level

Field Name	Field Description
`Path computation using abstract hops for LSP`	Name of the LSP for which the abstract hop computation is performed.
`Path type`	The type of the path can be primary or secondary.
`Path name`	Name of the path.
`Credibility`	Credibility value associated with the interior gateway protocol in use.
`Total no of CSPF passes`	Number of constrained shortest path passes for the abstract hop.
`CSPF pass no`	Constrained shortest path pass number for the abstract hop computation.
`Start address of the pass`	IP address where the pass starts.
