Cisco 877 router adsl Telia

Hi All

I have a C877 router that i would connect to a telia (big ISP of sweden) adsl connection. The router should recieve a dynamic ip address on the ATM interface.

From the ISP i get this information on what to configure

Router

Enet/Encap, routing, LLC based, VP8/VC35 (UBR)

When i debug the dhcp recuests i get this error messages.

Unknown DHCP problem.. No allocation possible

Here is the config (trunked)

dot11 syslog

no ip dhcp use vrf connected
ip dhcp excluded-address 192.168.10.1

Hi, The solution is as posted below.

interface ATM0
no ip address
no ip unreachables
no ip proxy-arp
ip flow ingress
no atm ilmi-keepalive
dsl operating-mode auto
!
interface ATM0.2 point-to-point
ip address dhcp
ip nat outside
ip virtual-reassembly
atm route-bridged ip
pvc 8/35
  encapsulation aal5snap
!
!

Now the router recieves an dynamic dhcp adress from the ISP (telia adsl).

Very good, please note that the commands put under atm0, are not effective, because the interface is not processing IP.
