Ppp Ipcp Dns Admit-Any - H3C MSR Series Command Reference Manual

If a host is connected to the device through PPP, you can execute the winipcfg command or the ipconfig
/all command on the host to check the DNS server IP addresses assigned by the device.
Examples
# Set the primary and secondary DNS server IP addresses to 100.1.1.1 and 100.1.1.2 for the peer on
interface Serial 2/0.

by the peer if it does not request the peer for the DNS server IP addresses.

Usage guidelines
You can configure a device to accept the DNS server IP addresses assigned by the peer, through which
domain names can be resolved for the device.
Generally, the server will specify a DNS server address for a client in PPP negotiation only after the client
is configured with the ppp ipcp dns request command. For some special devices to forcibly specify DNS
server addresses for clients that do not initiate requests, you must configure the ppp ipcp dns admit-any
command on these devices.
Examples
# Configure interface Serial 2/0 of the local device to accept the DNS server IP addresses allocated by
the peer even though it does not request the peer for the DNS server IP addresses.
<Sysname> system-view
[Sysname] interface serial 2/0
[Sysname-Serial2/0] ppp ipcp dns admit-any
