Parameters
ip-address: Specifies the IPv4 address used to spoof name query requests.
vpn-instance vpn-instance-name: Specifies the name of an MPLS L3VPN, a case-sensitive string of 1 to 31
characters. To enable DNS spoofing function on the public network, do not use this option.
Usage guidelines
Use the dns spoofing command together with the dns proxy enable command. DNS spoofing enables
the DNS proxy to send a spoofed reply with a configured IP address even if it cannot reach the DNS
server because no dial-up connection is available. Without DNS spoofing, the proxy does not answer or
forward a DNS request if it cannot find a local matching DNS entry or reach the DNS server.
You can configure DNS spoofing for the public network and a maximum of 1024 VPNs, and can specify
only one replied IPv4 address on the DNS spoofing device for the public network or each VPN.
If you use the command multiple times, the most recent configuration takes effect.
Examples
# Enable DNS spoofing on the public network and specify the IPv4 address 1.1.1.1 to spoof DNS
requests.
<Sysname> system-view
[Sysname] dns proxy enable
[Sysname] dns spoofing 1.1.1.1
