Release Information
Command introduced before Junos OS Release 7.4.
Option bridge-domain introduced in Junos OS Release 7.5
Option learning-vlan-id introduced in Junos OS Release 8.4
Options all and vlan introduced in Junos OS Release 9.6.
Command introduced in Junos OS Release 11.3 for the QFX Series.
Description
Display the Routing Engine's forwarding table, including the network-layer prefixes and their next hops. This command is used to help verify that the routing protocol process has relayed the correction information to the forwarding table. The Routing Engine constructs and maintains one or more routing tables. From the routing tables, the Routing Engine derives a table of active routes, called the forwarding table.
 | Note: The Routing Engine copies the forwarding table to the Packet Forwarding Engine, the part of the router that is responsible for forwarding packets. To display the entries in the Packet Forwarding Engine's forwarding table, use the show pfe route command. |
Options
none | — | Display the routes in the forwarding tables. By default, the show route forwarding-table command does not display information about private, or internal, forwarding tables. |
detail | extensive | summary | — | (Optional) Display the specified level of output. |
all | — | (Optional) Display routing table entries for all forwarding tables, including private, or internal, tables. |
bridge-domain (all | bridge-domain-name) | — | (MX Series routers only) (Optional) Display route entries for all bridge domains or the specified bridge domain. |
ccc interface-name | — | (Optional) Display route entries for the specified circuit cross-connect interface. |
destination destination-prefix | — | (Optional) Destination prefix. |
family family | — | (Optional) Display routing table entries for the specified family: fibre-channel, fmembers, inet, inet6, iso, mpls, tnp, unix, vpls, or vlan-classification. |
interface-name interface-name | — | (Optional) Display routing table entries for the specified interface. |
label name | — | (Optional) Display route entries for the specified label. |
lcc number | — | (Routing Matrix only) (Optional) On a routing matrix composed of a TX Matrix Plus router and T640 routers configured in the routing matrix, display information for the specified T640 router (or line-card chassis) connected to the TX Matrix router. On a routing matrix composed of the TX Matrix Plus router and T1600 routers configured in the routing matrix, display information for the specified T1600 router (or line-card chassis) connected to the TX Matrix Plus router. Replace number with a value from 0 through 3. |
learning-vlan-id learning-vlan-id | — | (MX Series routers only) (Optional) Display learned information for all VLANs or for the specified VLAN. |
matching matching | — | (Optional) Display routing table entries matching the specified prefix or prefix length. |
multicast | — | (Optional) Display routing table entries for multicast routes. |
table (default | logical-system-name/routing-instance-name | routing-instance-name) | — | (Optional) Display route entries for all the routing tables in the main routing instance or for the specified routing instance. If your device supports logical systems, you can also display route entries for the specified logical system and routing instance. To view the routing instances on your device, use the show route instance command. |
vlan (all | vlan-name) | — | (Optional) Display information for all VLANs or for the specified VLAN. |
vpn vpn | — | (Optional) Display routing table entries for a specified VPN. |

Output Fields
Table 1 lists the output fields for the show route forwarding-table command. Output fields are listed in the approximate order in which they appear. Field names might be abbreviated (as shown in parentheses) when no level of output is specified, or when the detail keyword is used instead of the extensive keyword.
Table 1: show route forwarding-table Output Fields
Field Name | Field Description | Level of Output |
|---|---|---|
Logical system | Name of the logical system. This field is displayed if you specify the table logical-system-name/routing-instance-name option on a device that is configured for and supports logical systems. | All levels |
Routing table | Name of the routing table (for example, inet, inet6, mpls). | All levels |
Address family | Address family (for example, IP, IPv6, ISO, MPLS, and VPLS). | All levels |
Destination | Destination of the route. | detail extensive |
Route Type (Type) | How the route was placed into the forwarding table. When the detail keyword is used, the route type might be abbreviated (as shown in parentheses):
| All levels |
Route Reference (RtRef) | Number of routes to reference. | detail extensive |
Flags | Route type flags:
| extensive |
Next hop | IP address of the next hop to the destination. | detail extensive |
Next hop Type (Type) | Next-hop type. When the detail keyword is used, the next-hop type might be abbreviated (as indicated in parentheses):
| detail extensive |
Index | Software index of the next hop that is used to route the traffic for a given prefix. | detail extensive none |
Route interface-index | Logical interface index from which the route is learned. For example, for interface routes, this is the logical interface index of the route itself. For static routes, this field is zero. For routes learned through routing protocols, this is the logical interface index from which the route is learned. | extensive |
Reference (NhRef) | Number of routes that refer to this next hop. | detail extensive none |
Next-hop interface (Netif) | Interface used to reach the next hop. | detail extensive none |
Weight | Value used to distinguish primary, secondary, and fast reroute backup routes. Weight information is available when MPLS label-switched path (LSP) link protection, node-link protection, or fast reroute is enabled, or when the standby state is enabled for secondary paths. A lower weight value is preferred. Among routes with the same weight value, load balancing is possible (see the Balance field description). | extensive |
Balance | Balance coefficient indicating how traffic of unequal cost is distributed among next hops when a router is performing unequal-cost load balancing. This information is available when you enable BGP multipath load balancing. | extensive |
RPF interface | List of interfaces from which the prefix can be accepted. Reverse path forwarding (RPF) information is displayed only when rpf-check is configured on the interface. | extensive |
