I need to setup a PPPoE server for IPv6 on Linux machine with RHEL 6.1. When I tried to start pppd, the output was the following:
~$ sudo pppd start pppd:in file /etc/ppp/options:unrecognized option 'ipv6'
Here is the content of /etc/ppp/options file:
local ipv6 ipv6cp-use-ipaddr
According to the pppd man page, the option 'ipv6' should be recognized. It puzzled me. I am not sure how to configure the PPPoE server to support IPv6 PPP connections now.
