Hello Samir,
a good scenario can be:
Cisco 3560 --- access port --- C857 --- DSL
be aware that some 857 IOS images have a limitations of only two L3 Vlans
if this limit is not present you can build an 802.1Q trunk between both devices.
About the DSL connection there are multiple options so you need to ask to your provider what they use:
ask if it is PPPoE or PPPoA or other
the ATM paramaters VPI and VCI to be used
the type of PPP based authentication to be used (PAP or CHAP ) and the credentials to be used.
an example of PPPoE client config:
interface ATM0/0
no ip address
no ip mroute-cache
no atm ilmi-keepalive
dsl operating-mode auto
pvc 8/35
encapsulation aal5mux ppp dialer
dialer pool-member 1
!
interface Dialer1
description PPPoverETHERNET
ip address negotiated
encapsulation ppp
dialer pool 1
dialer-group 1
ppp authentication pap callin
ppp chap refuse
ppp pap sent-username username password 7 051B071C325B411B1D
!
then you will need a default static route
ip route 0.0.0.0 0.0.0.0 dialer1
to get internet access you will need NAT with overloading option using dialer1
Hope to help
