ppp.conf PPPoE Errors

[JP]

Hello,
 
I just recently set up ppp.conf for PPPoE DSL Service with SBC.  I'm getting the following errors in my /var/log/ppp.log file, any idea what it means? I assume I need to disable IPV6 somehow but I don't know.

My ppp.conf file:
 
default:
        set device PPPoE:ed0:SBCIS
        set mtu 1492
        add default HISADDR
        set time 0
        set redial 0 0
# NAT Config
        nat enable yes
        nat log yes
        nat same_ports yes
        nat unregistered_only yes
        enable dns
SBCIS:
        set authname xxxxxx
        set authkey xxxxxx
 
Thanks!
