Table 241: 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
or
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
or
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
S=
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
a to 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. Level
IP subnet augmented with a 64-bit prefix.
