Table 285: show route detail Output Fields

(continued)

Field Description

Field Name

Route destination (for example:

10.0.0.1/24

). 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. Sometimes

the route destination is presented in another format, such as:

•

MPLS-label

(for example,

80001

•

interface-name

(for example,

ge-1/0/2

•

neighbor-address:control-word-status:encapsulation type:vc-id:source

(Layer 2 circuit only; for

example,

10.1.1.195:NoCtrlWord:1:1:Local/96

•

neighbor-address

—Address of the neighbor.

•

control-word-status

—Whether the use of the control word has been negotiated for this virtual

circuit:

NoCtrlWord

CtrlWord

•

encapsulation type

—Type of encapsulation, represented by a number: (1) Frame Relay DLCI, (2)

ATM AAL5 VCC transport, (3) ATM transparent cell transport, (4) Ethernet, (5) VLAN Ethernet,
(6) HDLC, (7) PPP, (8) ATM VCC cell transport, (10) ATM VPC cell transport

•

vc-id

—Virtual circuit identifier.

•

source

—Source of the advertisement:

Local

Remote

route-destination
(entry, announced)

(

Next-to-the-last-hop routing device for MPLS only) Depth of the Multiprotocol Label Switching

(MPLS) label stack, where the label-popping operation is needed to remove one or more labels from
the top of the stack. A pair of routes is displayed, because the pop operation is performed only when
the stack depth is two or more labels.

•

S=0 route

indicates that a packet with an incoming label stack depth of 2 or more exits this routing

device with one fewer label (the label-popping operation is performed).

•

If there is no

information, the route is a normal MPLS route, which has a stack depth of 1 (the

label-popping operation is not performed).

label stacking

Protocol from which the route was learned and the preference value for the route.

•

—A plus sign indicates the active route, which is the route installed from the routing table into the

forwarding table.

•

—A hyphen indicates the last active route.

•

—An asterisk indicates that the route is both the active and the last active route. An asterisk before

line indicates the best subpath to the route.

In every routing metric except for the BGP

LocalPref

attribute, a lesser value is preferred. In order to

use common comparison routines, Junos OS stores the 1's complement of the

LocalPref

value in the

Preference2

field. For example, if the

LocalPref

value for Route 1 is 100, the

Preference2

value is -101.

If the

LocalPref

value for Route 2 is 155, the

Preference2

value is -156. Route 2 is preferred because it

has a higher

LocalPref

value and a lower

Preference2

value.

[protocol, preference]

(IS-IS only). In IS-IS, a single AS can be divided into smaller groups called areas. Routing between
areas is organized hierarchically, allowing a domain to be administratively divided into smaller areas.
This organization is accomplished by configuring Level 1 and Level 2 intermediate systems. Level 1
systems route within an area; when the destination is outside an area, they route toward a Level 2
system. Level 2 intermediate systems route between areas and toward other ASs.
