Concept Guide

show ip nexthop-list
Description
Display nexthop list settings for policy-based routing.
Syntax
No parameters.
Usage Guidelines
A nexthop IP is the IP address of a adjacent router or device with layer-2 connectivity to the controller. The
Nexthop list provides redundancy for the nexthop devices by forwarding the traffic to a backup nexthop
device in case of failures. If active nexthop device on the list becomes unreachable, traffic matching a policy-
based routing ACL is forwarded using the highest-priority active nexthop on the list. For more information on
this feature, see ip nexthop-list on page 525.
Example
The following command displays the configuration settings for the one configured nexthop list.
(host))# show ip nexthop-list
--------------------
Nexthop-list Name Nexthop-list Id Preemptive Failover Active IP
----------------- --------------- ------------------- ---------
NH_list_1 0x4401 Enabled 10.10.10.254
Nexthop IPs(Priority)
---------------------
10.18.2.254(2), 10.10.10.254(1)
The output of this command displays the following information
Parameter Description
Nexthop-list Name
Name of the nexthop list
Nexthop-list Id
Nexthop list ID assigned by the controller.
Preemptive Fail-
over
This column indicates whether preemptive failover is enabled or disabled.
If preemption is enabled and a higher priority nexthop becomes reachable again,
packets are again forwarded to the higher priority nexthop.
Active IP
IP address of the actively used nexthop device.
Nexthop IPs(Pri-
ority)
List of the IP addresses of all nexthop IPs, including the priority assigned to each
device when the list was configured.
