Parameter
None
Description
Use the ppp ipcp dns request command to enable the router to request the peer for a
DNS server address. When the router is connected using PPP to another device, a
network access server of a service provider for example, this allows the router to
request the peer for a DNS server address through negotiation.
Use the undo ppp ipcp dns request command to disable the router to request the
peer for a DNS server address.
By default, the router is disabled to request the peer for a DNS server address.
 Note:
The valid DNS server address obtained after negotiation is displayed in the output
information about the corresponding interface.
Related command: ppp authentication-mode pap, ppp ipcp dns, ppp ipcp dns
admit-any, local-user.
