Hi everyone,
I have 876 Series router with atm0 int., and have ADSL with static ip address.
Can you tell me how to configure this interface to work properly..
I try some procedures from Cisco site but with no success.
Thx

Is your Isp using PPPoE or what encapsulation? What is the configuration that you have and does not work ?

I dont have a config for atm0, i was try some basic procedures from cisco site but with no success.
Now i have configured vlan, and use modem to go outside, PPPoE, and this work properly. But I want to know how can i configure atm0 without use of modem.
P.S. I was contact my ISP, and they say me that they don know which encapsulation use.
ha ha ha, funny, isnt it?
Thx

Hehe, at least your ISP is more honest than the telco that tells you "we fixed it" and then isn't true.
Here's a config for PPPoE:
http://cisco.com/en/US/tech/tk175/tk15/technologies_configuration_example09186a008071a6c3.shtml
Note, some commands are not necessary as per blue comments. Note also, the example configuress atm0.1 subinterface, in reality that is not necessary and you can put all the interface commands under atm0 directly.
Let us know if it works, then call back the ISP and fax the config to them (they probably can't use email).

Hi Amar.
Just add some information for you.
I hope you are using pppoe routing mode.
Just try this :
interface ATM0
no ip address
no atm ilmi-keepalive
dsl operating-mode auto
!
interface ATM0.1 point-to-point
description Connected to ISP
pvc X/Y --> Ask your ISP for this params.
pppoe-client dial-pool-number 1
!
interface FastEthernet0
!
interface FastEthernet1
!
interface FastEthernet2
!
interface FastEthernet3
!
interface Vlan1
ip address
ip nat inside
interface Dialer1
ip address < PUBLIC IPADDRESS>
ip nat outside
ip virtual-reassembly
encapsulation ppp
dialer pool 1
dialer-group 1
ppp authentication pap chap callin
ppp chap hostname xxxx
ppp chap password 0 yyyyy
ppp pap sent-username xxxx password 0 yyyyy
ip route 0.0.0.0 0.0.0.0 Dialer1
dialer-list 1 protocol ip permit
!
ip nat inside source list Internal interface Dialer1 overload
ip access-list extended Internal
remark
permit ip A.B.C.D 255.255.255.0 any
Don't tell me your ISP provides bridge mode for you. ;-)
Hope this helps

Thx,
but i have adsl packet with static ip addresses. this mean, no username, and no password. the solution with dialer drop for now.
07-03-2007 07:08 AM
Thx, i will try this...
But i dont have username and pass for dialer, i have static ip address. i think i was try something like this but with no success.
have more ideas?

Hi Amar.
Back at one. Could you ask your ISP for more detail about adsl configuration.I hope you already tried the link as paolo stated.
For testing the bridge mode as follows:
bridge irb
interface Vlan1
ip address
ip nat inside
interface ATM0/0/0
no ip address
no atm ilmi-keepalive
dsl operating-mode auto
!
interface ATM0/0/0.1 point-to-point
no snmp trap link-status
bridge-group 1
pvc X/Y
encapsulation aal5snap
!
!
interface BVI1
ip address
ip nat outside
ip route 0.0.0.0 0.0.0.0 bvi1
ip nat inside source list Internal interface bvi1 overload
ip access-list extended Internal
remark
permit ip A.B.C.D 255.255.255.0 any
bridge 1 protocol ieee
bridge 1 route ip
Hope this helps

Then is not PPPoE (dialer). It's likely bridged 1483, this is the example:
Also the configuration given you by thotsaphon should work and actually I like it better for certain minors aspects.
After that the only remaining choice is routed 1483, but unlikely.
Good luck!

Thx guys.
I?ll try this today and post the results.
i hope this will work.
