show as-path summary

Syntax

Syntax (EX Series Switches)

Description

Display autonomous system (AS) path summary information.

AS paths are stored in a hash table. A hash table is one method for fast lookup. Each entry in the table is called a bucket. Junos OS computes a hash value that indicates in which bucket the AS path is stored. The AS paths are dispersed among the hash buckets so that a manageable number of AS paths is stored in each bucket. Only unique AS paths are stored. Duplicate AS paths increase a reference count, but do not increase the number of AS paths stored in the hash table.

Options

none	(Optional) Display AS path summary information for all routing instances.
logical-system (all \| `logical-system-name`)	(Optional) Perform this operation on all logical systems or on a particular logical system.
