PPP IP Unique Address and Prefix Detection

The PPP IP Unique Address and Prefix Detection feature checks the uniqueness of IPv4 address and IPv6 prefix on the Broadband Remote Access Server (BRAS). PPP disconnects the session if it detects a duplicate IPv4 address and IPv6 prefix.

ppp ipcp dns X.X.X.X

addressing DNS servers which is domain name servers. its better to configure it as ppp ipcp dns request on the dialer interface which will allow the router to start asking for the DNS server address as part of the IPCP negotiation. The negotiation process can be debugged with the debug ppp negotiation command

 ppp ipcp address required

Disconnects the peer if no IP address is negotiated.

 ppp ipcp address unique

Disconnects the peer if the IP address is already in use.

 ppp ipcp address accept 

Accepts any nonzero IP address from the peer.

Please rate if its helpful
