115
vpn-instance vpn-instance-name: Specifies the name of an MPLS L3VPN instance, a case-sensitive string
of 1 to 31 characters. If you do not specify any VPN, the command clears the domain name-to-IPv6
address mapping on the public network.
Usage guidelines
If you do not specify the ip or ipv6 keyword, the reset dns host command without the ip and ipv6
keywords clears dynamic DNS cache information about all query types.
Examples
# Clear dynamic DNS cache information about all query types on the public network.
