ADSL Config

jagan_240 · ‎08-30-2009

Hi All,

I have 2811 router with HIW-1ADSL card, i need to configure this router for internet connection. I have already one ADSL Linksys router up and running the configuration of that Linksys router as follows

Encapsulation : RFC 2516 PPPOE

pcr rate :cps

scr rate :cps

virtual circuit: vpi=0

vci=50

DSL Modulation : Multimode

PPPOE setting:

username : John

password : XXXX

connect on Demand : yes

Max idle timeo out : 5 mints

can you help to do the same configuration in above said cisco 2811 router.

thanks

Hello Jagan,

for releases after IOS 12.2(13)T the following is enough:

suppose that atm0/0 is the name of the DSL interface on your router

interface ATM0/0

no ip address

no ip mroute-cache

no atm ilmi-keepalive

dsl operating-mode auto

pvc 0/50

enc aal5snap

pppoe-client dial-pool-number 2

!

interface Dialer2

description PPPoEoverATM

mtu 1492

ip address negotiated

encapsulation ppp

dialer pool 2

dialer-group 2

dialer idle-timeout 300

ppp chap hostname John

ppp chap password XXXX

ppp pap sent-username John password XXXX

!

dialer-list 2 protocol ip permit

ip route 0.0.0.0 0.0.0.0 dialer2 200

you need also to NAT the internal interface to allow internet access from inside.

int fas0/0

ip address 192.168.34.1 255.255.255.0

ip nat inside

access-list 11 permit 192.168.34.0 0.0.0.255

int dialer2

ip nat outside

ip nat inside source list 11 int dialer2 overload

see

Hi Giuseppe,

This issue is resolved it an ppp authentication issue.

Thanks a lot in assisting me on this issue.
