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. |
| active-helpers helper nodes |
(Optional) Displays only those IP address of helper nodes upon which paths are resolving. |
| brief | detail | extensive | summary |
(Optional) Display the specified level of output. |
| import-policy destination-prefix |
(Optional) Displays details about the resolution import policies. |
| index index |
(Optional) Show the index of the resolution tree. |
| list-nh next-hop address |
(Optional) Displays list nexthop binding between indirect nexthop and hekper. |
| logical-system (all | logical-system-name) |
(Optional) Perform this operation on all logical systems or on a particular logical system. |
| loop-history resolution-loop events |
(Optional) Displays the resolution loop events. |
| prefix network/destination-prefix |
(Optional) Display database entries for the specified address. |
| re-resolution-history resolution-history |
(Optional) Displays the resolution history. |
| rib-sharding rib-shard-name |
(Optional) Displays name of the rib-shard. |
| scheme custom-resolution-schemes |
(Optional) Displays custom resolution schemes for route next-hop resolution. |
| summary summary of route-resolution |
(Optional) Displays summary of resolution tree. |
| 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.
|
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. Merged—Merged next hops when recursive resolution of multipath is configured. |
