origin, providing an indication of the state of the route at the point at which the AS path originated:
When AS path numbers are included in the route, the format is as follows:
NOTE: In Junos OS Release 10.3 and later, the AS path field displays an unrecognized attribute and
associated hexadecimal value if BGP receives attribute 128 (attribute set) and you have not configured
an independent domain in any routing instance.

is configured on the routing device, or if AS path prepending is configured.
—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.

( [ ] ) —Parentheses and brackets enclose a confederation set.
—Value used to distinguish primary, secondary, and fast reroute backup routes. Weight
Weight
information is available when Multiprotocol Label Switching (MPLS) label-switched path (LSP)
link protection, node-link protection, or fast reroute is enabled, or when the standby state is enabled
for secondary paths. A lower weight value is preferred. Among routes with the same weight value,
load balancing is possible.
—Balance coefficient indicating how traffic of unequal cost is distributed among next hops
Balance
when a routing device is performing unequal-cost load balancing. This information is available
when you enable Border Gateway Protocol (BGP) multipath load balancing.
—Name of the label-switched path (LSP) used to reach the next hop.
