I'm trying to simulate a PPPoE Server in my office and I can't make it to work. I'm not sure if I am missing something, so I badly need your help.
Here's the setup:
Cisco ISR4221 router is to be configured as PPPoE Server. One
ethernet port (GigabitEthernet0/0/1)
of the router is connected to the Internet source, while the second
ethernet port (GigabitEthernet0/0/0)
is connected to a Cisco switch that is also connected to 2 Windows computers (that will be used as
PPPoE clients).
My problems:
1.
PPPoE clients
can not
ping 8.8.8.8 or 192.168.150.1(Loopback0).
2. The
GigabitEthernet0/0/1 port
can not get ip address after cisco ISR4221
router reboot.
The
GigabitEthernet0/0/1 port
can work after reset cisco ISR4221 router to default.
Below is the router config:
