destinations—Number of destinations for which there are routes in the routing table.

routes—Number of routes in the routing table:

• active—Number of routes that are active.
• holddown—Number of routes that are in the hold-down state prior to being declared inactive.
• hidden—Number of routes not used because of routing policy.

prefix—Route address.

[protocol/preference ]—Protocol from which the route was learned and the route's preference value.

+—A plus sign before [protocol/preference ] indicates the active route, which is the route installed from the routing table into the forwarding table.

- —A hyphen before [protocol/preference ] indicates the last active route.

*—An asterisk before [protocol/preference ] indicates that the route is both the active and the last active route. An asterisk before a to line indicates the best subpath to the route.

time—How long the route has been known.

from—Address and interface from which route was learned.

AS Path—AS path included in the route.

[ ]—Brackets enclose the local AS number associated with the AS path if more than one AS number is configured on the router.

{ }—Braces enclose AS sets, which are groups of AS numbers in which the order does not matter. A set commonly results from route aggregation. The numbers in each AS set are displayed in ascending order.

( )—Parentheses enclose a confederation.

( [ ] )—Enclose a confederation set.
