The /etc/ppp/pppoe.if file lists the names of all Ethernet interfaces on a host to be used for the PPPoE tunnels. This file is processed during system boot when the interfaces that are listed are plumbed for use in PPPoE tunnels.
You need to create explicitly /etc/ppp/pppoe.if. Type the name of one interface to be configured for PPPoE on each line.
# cat /etc/ppp/pppoe.if hme1 hme2 hme3
PPPoE clients usually have only one interface that is listed in /etc/ppp/pppoe.if.
