Command Reference, Cisco Ios Xe Everest 16.5.1A (Catalyst 3650 Switches - Cisco Catalyst 3650 series Command Reference Manual

Command Default
No next-hop servers are explicitly configured, so normal network layer routing decisions are used to forward
NHRP traffic.
Command Modes
Interface configuration (config-if)
Command History
Release
Cisco IOS XE Denali 16.3.1
Usage Guidelines
Use the ip nhrp nhs command to specify the address of a next hop server and the networks it serves. Normally,
NHRP consults the network layer forwarding table to determine how to forward NHRP packets. When next
hop servers are configured, these next hop addresses override the forwarding path that would otherwise be
used for NHRP traffic.
For any next hop server that is configured, you can specify multiple networks by repeating the ip nhrp nhs
command with the same nhs-address argument, but with different IP network addresses.
Examples The following example shows how to register a hub to a spoke using NBMA and FQDN:
Switch# configure terminal
Switch(config)# interface tunnel 1
Switch(config-if)# ip nhrp nhs 192.0.2.1 nbma examplehub.example1.com
The following example shows how to configure the desired max-connections value:
Switch# configure terminal
Switch(config)# interface tunnel 1
Switch(config-if)# ip nhrp nhs cluster 5 max-connections 100
The following example shows how to configure the NHS fallback time:
Switch# configure terminal
Switch(config)# interface tunnel 1
Switch(config-if)# ip nhrp nhs fallback 25
The following example shows how to configure NHS priority and group values:
Switch# configure terminal
Switch(config)# interface tunnel 1
Switch(config-if)# ip nhrp nhs 192.0.2.1 priority 1 cluster 2
