This object specifies the IPCP address option for a target PPP
connection:
'other'
The implementation of this MIB module does not recognize
the configured IPCP address option.
'accept'
The system accepts any non-zero IP address from the peer
of a target PPP connection.
'required'
The system disconnects the peer of a target PPP
connection if it could not negotiate an IP address.
'unique'
The system disconnects the peer of a target PPP
connection if the IP address is already in use.
This column is valid only if the 'ipcpAddrOption' bit of the
corresponding instance of cdtPppValid is '1'.
