Parameter None
Description Use the
ppp ipcp dns request command to enable a device to request its peer
for the DNS server address actively through a port.

You can configure a device to request its peer (especially in cases where a device is
connected to the operator’s access server through a dialup link) for the DNS server
address during PPP negotiation, after which domain names can be resolved on the
device.

Description Use the
ppp ipcp remote-address forced command to forbid the peer to use
self-configured IP address, but have to use the one allocated by the local device.
Use the
undo ppp ipcp remote-address forced command to cancel this
feature.
By default, the peer can use its self-configured IP address in PPP IPCP negotiation.
The peer can request the local device for an address or use a fixed IP address
configured by itself
If you do not want the peer to use self-configured IP address, you must configure
the ppp ipcp remote-address forced command on the local interface.
