show mpls lsp abstract-computation
Syntax
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
