使用pppoeconf拨号，无法获得pppoe网卡地址（内网地址）

[Solairen41]

主机使用pppoeconf进行拨号，网卡情况为：
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host noprefixroute
valid_lft forever preferred_lft forever
2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
link/ether 00:e0:b4:1d:06:ae brd ff:ff:ff:ff:ff:ff
3: ppp0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1492 qdisc fq_codel state UNKNOWN group default qlen 3
link/ppp
inet 10.68.162.106 peer 10.68.0.1/32 scope global ppp0
valid_lft forever preferred_lft forever

配置文件：
- "CHECKLOCAL=true"
- "IPV4NETS=10.68.0.1/32,127.0.0.1/8"
10.68.0.1/32地址获取不了，只能获取127.0.0.1（单独试过10.68.0.1/32）
