The ipv6 nd ra hop-limit command configures a maximum number of hops for an RA message.
The undo ipv6 nd ra hop-limit command restores the default maximum number of hops for an RA message.
By default, the default maximum number of hops for an RA message is 64.
| Parameter | Description | Value |

Usage Scenario
The hop limit is a parameter carried in an RA message. It defines the maximum number of hops that the RA message (which is an IPv6 unicast packet) passes through.
Prerequisites
The ipv6 enable command has been run on the interface to enable IPv6.
Configuration Impact
If the device finds that the hop limit in its received RA message is different from that configured on the device itself, the device will discard this RA message.
Precautions
If the ipv6 nd ra hop-limit command has been run on an interface, the hop limit for an RA message uses the value configured on the interface.
If the ipv6 nd ra hop-limit command has not been run on an interface, the hop limit for an RA message uses the value configured globally, that is, the value configured in the ipv6 nd hop-limit command.
