Table 213: show route Output Fields (continued)
Field DescriptionField Name
Local preference value included in the route.localpref
Interface from which the route was received.from
AS path through which the route was learned. The letters at the end of the AS path indicate the path
origin, providing an indication of the state of the route at the point at which the AS path originated:
• I—IGP.
• E—EGP.
• ?—Incomplete; typically, the AS path was aggregated.
When AS path numbers are included in the route, the format is as follows:
• [ ]—Brackets enclose the local AS number associated with the AS path if more than one AS number
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.
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.
AS path
Extended next-hop encoding capability enabled for the specified BGP community for routing IPv4
traffic over IPv6 tunnels. When BGP receives routes without the tunnel community, IPv4-0ver IPv6
tunnels are not created and BGP routes are resolved without encapsulation.
encapsulated
Stack of labels carried in the BGP route update.Route Labels
(BGP-learned routes) Validation status of the route:
• Invalid—Indicates that the prefix is found, but either the corresponding AS received from the EBGP
peer is not the AS that appears in the database, or the prefix length in the BGP update message is
longer than the maximum length permitted in the database.
• Unknown—Indicates that the prefix is not among the prefixes or prefix ranges in the database.
• Unverified—Indicates that the origin of the prefix is not verified against the database. This is because
the database got populated and the validation is not called for in the BGP import policy, although
origin validation is enabled, or the origin validation is not enabled for the BGP peers.
• Valid—Indicates that the prefix and autonomous system pair are found in the database.
validation-state
Next hop to the destination. An angle bracket (>) indicates that the route is the selected route.
If the destination is Discard, traffic is dropped.
