Release Information

Command introduced before Junos OS Release 7.4.

Command introduced in Junos OS Release 9.0 for EX Series switches.

Description

Display the entries in the next-hop resolution database. This database provides for recursive resolution of next hops through other prefixes in the routing table.

Options

none

Display standard information about all entries in the next-hop resolution database.

brief | detail | extensive | summary

(Optional) Display the specified level of output.

index index

(Optional) Show the index of the resolution tree.

logical-system (all | logical-system-name)

(Optional) Perform this operation on all logical systems or on a particular logical system.

prefix network/destination-prefix

(Optional) Display database entries for the specified address.

table routing-table-name

(Optional) Display information about a particular routing table (for example, inet.0) where policy-based export is currently enabled.

unresolved

(Optional) Display routes that could not be resolved.

Output Fields

Table 1 describes the output fields for the show route resolution command. Output fields are listed in the approximate order in which they appear.

Table 1: show route resolution Output Fields

Field Name

Field Description

routing-table-name

Name of the routing table whose prefixes are resolved using the entries in the route resolution database. For routing table groups, this is the name of the primary routing table whose prefixes are resolved using the entries in the route resolution database.

Tree index

Tree index identifier.

Nodes

Number of nodes in the tree.

Reference count

Number of references made to the next hop.

Contributing routing tables

Routing tables used for next-hop resolution.

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.

Metric

Metric associated with the forwarding next hop.

Node path count

Number of nodes in the path.

Forwarding next hops

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.
