show route advertising-protocol

routing-table-name

Name of the routing table—for example, inet.0.

number destinations

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

number routes

Number of routes in the routing table and total number of routes in the following states:

• active (routes that are active)

• holddown (routes that are in the pending state before being declared inactive)

• hidden (routes that are not used because of a routing policy)

Prefix

Destination prefix.

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.

BGP group and type

BGP group name and type (Internal or External).

Route Distinguisher

Unique 64-bit prefix augmenting each IP subnet.

Advertised Label

Incoming label advertised by the Label Distribution Protocol (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.

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.

VPN Label

Virtual private network (VPN) label. Packets are sent between CE and PE routers by advertising VPN labels. VPN labels transit over either a Resource Reservation Protocol (RSVP) or a Label Distribution Protocol (LDP) label-switched path (LSP) tunnel.

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.

MED

Multiple exit discriminator value included in the route.

Lclpref or Localpref

Local preference value included in the route.

Queued

When BGP route prioritization is enabled and a route is present in a priority queue, this shows which priority queue the route is in.

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:

• 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 configured on the router, 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.

Route Labels

Stack of labels carried in the BGP route update.

Cluster list

(For route reflected output only) Cluster ID sent by the route reflector.

Originator ID

(For route reflected output only) Address of routing device that originally sent the route to the route reflector.

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.

AIGP

Accumulated interior gateway protocol (AIGP) BGP attribute.

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.

Layer2-info: encaps

Layer 2 encapsulation (for example, VPLS).

control flags

Control flags: none or Site Down.

mtu

Maximum transmission unit (MTU) of the Layer 2 circuit.
