IPv6 Routing Commands
clear ipv6 neighbors
Use the
clear ipv6 neighbors
command in Privileged EXEC mode to clear all entries in the IPv6
neighbor table or an entry on a specific interface.
Syntax

vlan-id
]
•
vlan-id
—
Valid VLAN ID.
Default Configuration
This command has no default configuration.
Command Mode
Privileged EXEC mode
User Guidelines
This command has no user guidelines.
Example
The following example clears all entries in the IPv6 neighbor table.
console(config)#clear ipv6 neighbors
clear ipv6 statistics
