Hi,
As shown in the figure below (the blue line), I can’t access from one to another router in the same range of IP’s. but when connect the routers as DHCP not PPP I can access without any problems.
any clue?

It’s not the same range. If you look at the route that PPPoE client adds, you won’t see a netmask.
