Configuring DNS server IP address negotiation on the client
About DNS server IP address negotiation on the client
During PPP negotiation, the server will assign a DNS server IP address only for a client configured
with the
ppp ipcp dns request
command. For some special devices to forcibly assign DNS
server IP addresses to clients that do not initiate requests, configure the
ppp ipcp dns
admit-any
command on these devices.

does not request the peer for the DNS server IP addresses.
