Cisco 857 ATM issue.

Hi, i'm trying to configure the ADSL interface of a router 857 with fixed ip but all input packets are received erroneous.

I have tested the line with a router 1721 with the same configuration and it's ok. I have tested the router 857 in other ADSL and it's ok too.

To give enough information I have included a file with the configuration of the router, other one with the exit of a debug and other one with the exit of several commands related to the state of the ATM interface.

Someone knows if some problem exists with the IOS version of this router?

Re: Cisco 857 ATM issue.

Hello,

try the following additional settings on your interface:

interface ATM0

no ip address

no atm ilmi-keepalive

dsl operating-mode auto

-->dsl operating-mode ansi-dmt

!

interface ATM0.1 point-to-point

ip address

ip nat outside

-->ip mtu 1452

or

-->ip tcp adjust-mss 1452

ip virtual-reassembly

pvc 8/32

encapsulation aal5snap

Check if that makes a difference, if not, post back...

Regards,
