Syntax (EX Series Switches)
Release Information
Command introduced before Junos OS Release 7.4.
Command introduced in Junos OS Release 9.0 for 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. |
