Usage guidelines
When connected through PPP, a device can assign DNS server IP addresses to its peer during PPP
negotiation (if the peer requests) for the peer to access the network by domain names.
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.
A device can provide a primary DNS server IP address and a secondary DNS server IP address to its
peer.
Examples
# Set the primary DNS server IP address to 100.1.1.1 and the secondary DNS server IP address to
100.1.1.2 on interface Serial 2/0/1.

ppp ipcp dns admit-any
Use ppp ipcp dns admit-any to configure the device to accept the DNS server IP addresses assigned by
the peer even though it does not request the peer for the DNS server IP addresses.
Use undo ppp ipcp dns admit-any to configure the device to deny the DNS server IP addresses assigned
by the peer if it does not request the peer for the DNS server IP addresses.
