hi, i have some problem with my cisco 2621 router.
i want to configure my 2621 as a CPE PPPoE client. my device sit behing a cable modem.
when i try to connect, wan interface (ethernet) and DIALER interface are up , but i don't receive dynamically an IP address from my ISP.
i'm figuring out that the problem is ppp authentication but when i use debug ppp authentication and negociation to solve problem, i do not seen anything. debug ppp does not working.
the problem can, be my IOS since i dont see any logging for ppp debugging.
what is problem ? i muist upgrade my IOS ? thank for help
