Output Fields
Table 1 describes the output fields for the show route extensive command. Output fields are listed in the approximate order in which they appear.
Table 1: show route extensive Output Fields
Field Name | Field Description |
---|---|
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:
|
route-destination (entry, announced) | Route destination (for example: 10.0.0.1/24). The entry value is the number of route 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:
|
TSI | Protocol header information. |
label stacking | (Next-to-the-last-hop routing device for MPLS only) Depth of the 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.
|
[protocol, preference] | Protocol from which the route was learned and the preference value for 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. |
Level | (IS-IS only). In IS-IS, a single autonomous system (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. |
Route Distinguisher | IP subnet augmented with a 64-bit prefix. |
Next-hop type | Type of next hop. For a description of possible values for this field, see the Output Field table in the show route detail command. |
Next-hop reference count | Number of references made to the next hop. |
Flood nexthop branches exceed maximum message | Indicates that the number of flood next-hop branches exceeded the system limit of 32 branches, and only a subset of the flood next-hop branches were installed in the kernel. |
Source | IP address of the route source. |
Next hop | Network layer address of the directly reachable neighboring system. |
via | Interface used to reach the next hop. If there is more than one interface available to the next hop, the name of the interface that is actually used is followed by the word Selected. This field can also contain the following information:
|
Label-switched-path lsp-path-name | Name of the LSP used to reach the next hop. |
Label operation | MPLS label and operation occurring at this routing device. The operation can be pop (where a label is removed from the top of the stack), push (where another label is added to the label stack), or swap (where a label is replaced by another label). |
Offset | Whether the metric has been increased or decreased by an offset value. |
Interface | (Local only) Local interface name. |
Protocol next hop | Network layer address of the remote routing device that advertised the prefix. This address is used to recursively derive a forwarding next hop. |
label-operation | MPLS label and operation occurring at this routing device. The operation can be pop (where a label is removed from the top of the stack), push (where another label is added to the label stack), or swap (where a label is replaced by another label). |
Indirect next hops | When present, a list of nodes that are used to resolve the path to the next-hop destination, in the order that they are resolved. |
State | State of the route (a route can be in more than one state). See the Output Field table in the show route detail command. |
Session ID | The BFD session ID number that represents the protection using MPLS fast reroute (FRR) and loop-free alternate (LFA). |
Inactive reason | If the route is inactive, the reason for its current state is indicated. Typical reasons include:
|
Local AS | Autonomous system (AS) number of the local routing device. |
Age | How long the route has been known. |
AIGP | Accumulated interior gateway protocol (AIGP) BGP attribute. |
Metric | Cost value of the indicated route. For routes within an AS, the cost is determined by IGP and the individual protocol metrics. For external routes, destinations, or routing domains, the cost is determined by a preference value. |
MED-plus-IGP | Metric value for BGP path selection to which the IGP cost to the next-hop destination has been added. |
TTL-Action | For MPLS LSPs, state of the TTL propagation attribute. Can be enabled or disabled for all RSVP-signaled and LDP-signaled LSPs or for specific VRF routing instances. For sample output, see show route table. |
Task | Name of the protocol that has added the route. |
Announcement bits | List of protocols that are consumers of the route. Using the following output as an example, Announcement bits (3): 0-KRT 5-Resolve tree 2 8-BGP RT Background there are (3) announcement bits to reflect the three clients (protocols) that have state for this route: Kernel (0-KRT), 5 (resolution tree process 2), and 8 (BGP). The notation n-Resolve inet indicates that the route is used for route resolution for next hops found in the routing table. n is an index used by Juniper Networks customer support only. |
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:
When AS path numbers are included in the route, the format is as follows:
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: I <Originator> | (For route reflected output only) Originator ID attribute set by the route reflector. |
VC Label | MPLS label assigned to the Layer 2 circuit virtual connection. |
MTU | Maximum transmission unit (MTU) of the Layer 2 circuit. |
VLAN ID | VLAN identifier of the Layer 2 circuit. |
Cluster list | (For route reflected output only) Cluster ID sent by the route reflector. |
Originator ID | (For route reflected output only) Address of router that originally sent the route to the route reflector. |
Prefixes bound to route | Forwarding equivalent class (FEC) bound to this route. Applicable only to routes installed by LDP. |
Communities | Community path attribute for the route. See the Output Field table in the show route detail command for all possible values for this field. |
Layer2-info: encaps | Layer 2 encapsulation (for example, VPLS). |
control flags | Control flags: none or Site Down. |
mtu | Maximum transmission unit (MTU) information. |
Label-Base, range | First label in a block of labels and label block size. A remote PE routing device uses this first label when sending traffic toward the advertising PE routing device. |
status vector | Layer 2 VPN and VPLS network layer reachability information (NLRI). |
Localpref | Local preference value included in the route. |
Router ID | BGP router ID as advertised by the neighbor in the open message. |
Primary Routing Table | In a routing table group, the name of the primary routing table in which the route resides. |
Secondary Tables | In a routing table group, the name of one or more secondary tables in which the route resides. |
Originating RIB | Name of the routing table whose active route was used to determine the forwarding next-hop entry in the resolution database. For example, in the case of inet.0 resolving through inet.0 and inet.3, this field indicates which routing table, inet.0 or inet.3, provided the best path for a particular prefix. |
Node path count | Number of nodes in the path. |
Forwarding nexthops | Number of forwarding next hops. The forwarding next hop is the network layer address of the directly reachable neighboring system (if applicable) and the interface used to reach it. |
