show ip route
Use this command to display the IP routing table for a protocol or from a particular table.
When multiple entries are available for the same prefix, NSM uses an internal route selection mechanism based on protocol administrative distance and metric values to choose the best route. All best routes are entered into the FIB and can be viewed using this command. To display all routes (selected and not selected), use the show ip route database command.
Use this command to see all subnets of a specified network if they are present in the routing table. Use this command with mask information.

Fast reroute repair paths.
interface
Routes learned or tied to a specific interface.
isis
IS-IS routing-protocol routes.

mstatic
Multicast static routes.
next-hop
Routes based on a specific next-hop address.

Summarize all routes
vrf WORD
Routes for a specific Virtual Routing and Forwarding (VRF) instance named WORD.
vrf all
Routes for all VRF instances.
mpls
Shows the routing table entries resolved through MPLS next-hops (NHLFE).
mpls summary
Shows the summary of MPLS-resolved routes in the routing table.

None
Command Mode
Execution mode and Privileged execution mode
Applicability
Introduced before OcNOS version 1.3.
Added mpls summary parameter and Total number of IPv4 routes (All VRFs) field in the show ip route vrf all summary command in the OcNOS version 7.0.0.
Example
Displays all routes in the IP routing table database.
The recursive via MPLS FTN-ID <ID>, nhlfe-ix <INDEX> field specifies the MPLS next-hop used for recursive resolution.
