show mpls lsp abstract-computation

Syntax

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
