Syntax
Release Information
Command introduced before Junos OS Release 7.4.
Description
Display the routing information as it has been prepared for advertisement to a particular neighbor of a particular dynamic routing protocol.
Options
brief | detail | extensive | terse | — | (Optional) Display the specified level of output. |
logical-system (all | logical-system-name) | — | (Optional) Perform this operation on all logical systems or on a particular logical system. |
neighbor-address | — | Address of the neighboring router to which the route entry is being transmitted. |
protocol | — | Protocol transmitting the route:
|
Additional Information
Routes displayed are routes that the routing table has exported into the routing protocol and that have been filtered by the associated protocol's export routing policy statements.

Output Fields
Table 1 lists the output fields for the show route advertising-protocol command. Output fields are listed in the approximate order in which they appear.
Table 1: show route advertising-protocol Output Fields
Field Name | Field Description | Level of Output |
|---|---|---|
routing-table-name | Name of the routing table—for example, inet.0. | All levels |
number destinations | Number of destinations for which there are routes in the routing table. | All levels |
number routes | Number of routes in the routing table and total number of routes in the following states:
| All levels |
Prefix | Destination prefix. | brief none |
destination-prefix (entry , announced) | Destination prefix. The entry value is the number of routes for this destination, and the announced value is the number of routes being announced for this destination. | detail extensive |
BGP group and type | BGP group name and type (Internal or External). | detail extensive |
Route Distinguisher | Unique 64-bit prefix augmenting each IP subnet. | detail extensive |
Advertised Label | Incoming label advertised by the LDP. When an IP packet enters a label-switched path (LSP), the ingress router examines the packet and assigns it a label based on its destination, placing the label in the packet's header. The label transforms the packet from one that is forwarded based on its IP routing information to one that is forwarded based on information associated with the label. | detail extensive |
Label-Base, range | First label in a block of labels and label block size. A remote PE router uses this first label when sending traffic toward the advertising PE router. | detail extensive |
VPN Label | Virtual private network (VPN) label. Packets are sent between CE and PE routers by advertising VPN labels. VPN labels transit over either an RSVP or an LDP LSP tunnel. | detail extensive |
Nexthop | Next hop to the destination. An angle bracket (>) indicates that the route is the selected route. If the next-hop advertisement to the peer is Self, and the RIB-out next hop is a specific IP address, the RIB-out IP address is included in the extensive output. See show route advertising-protocol bgp extensive all (Next Hop Self with RIB-out IP Address). | All levels |
MED | Multiple exit discriminator value included in the route. | brief |
Lclpref or Localpref | Local preference value included in the route. | All levels |
AS path | 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:
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. | All levels |
Communities | Community path attribute for the route. See the output field table for the show route detail command for all possible values for this field. | detail extensive |
AIGP | Accumulated interior gateway protocol (AIGP) BGP attribute. | detail extensive |
Attrset AS | Number, local preference, and path of the autonomous system (AS) that originated the route. These values are stored in the Attrset attribute at the originating router. | detail extensive |
Layer2-info: encaps | Layer 2 encapsulation (for example, VPLS). | detail extensive |
control flags | Control flags: none or Site Down. | detail extensive |
mtu | Maximum transmission unit (MTU) of the Layer 2 circuit. | detail extensive |
