I need to configure a HWIC-1ADSL card to work MPoA. The Telco has given me the next data:
Modo de Acesso: MPoA (RFC 2684)
Tipo de Encapsulamento: LLC SNAP
VPI: 0
VCI: 37
WAN IP: A.B.C.D/255.255.255.252
My config is:
bridge irb
interface ATM0/3/0
no ip address
no atm ilmi-keepalive
dsl operating-mode auto
!
interface ATM0/3/0.1 point-to-point
no snmp trap link-status
bridge-group 2
pvc 0/37
encapsulation aal5snap
!
!
interface BVI2
ip address A.B.C.D 255.255.255.252
ip nat outside
ip virtual-reassembly
bridge 2 protocol ieee
bridge 2 route ip
It does not work. How can I see if the config is right?
Thanks.

Hi, that should work. Check first if layer 1 is up with "show dsl interface".

Could be a problem with routing? Now I have the connection with the Telco through ethernet, so there is a default route ("ip route 0.0.0.0 0.0.0.0 dialer0"). If I type "ip route 0.0.0.0 0.0.0.0 bvi2" 50% of packets are lossed (it makes load-balancing between the two interfaces).
Thanks. Regards.

Hi, remove dialer interface if you have any, and remove both default routes referencing interfaces, instead put one with the IP of the other valid address on your /30 wan subnet.
That should get you going. I haven't asked about default route because often the card doesn't connected at all and needs FW update. If you want to benefit from the updates too the url is:
ftp://ftp.cisco.com/pub/access/800
The one you want is 3-0-3 and there is a doc about.
Hope this helps, please rate post if it does!

Hi Paolo,
I have done all you say, and it doesn't work. Is there any debug command where I could see what is happening? Thanks
Best Regards.
06-18-2008 09:02 AM
Post the last byte of you given IP so we can check the address for default route and ping.
06-18-2008 09:16 AM
The last byte of our public ip is 126. The default gateway is 125. What test can I do?
Thanks
06-18-2008 09:44 AM
Ping default gw and check: "show ip route 0.0.0.0", "show atm pvc 0/37", "show bridge 2 verbose".
If the circuit was working with another router, you might need to clone mac of the working device in case it's cached somewhere.
Also check with telco that your circuit is fully activated, as sometime they forget to do so. In some networks, when you're activated for the first time, you can initially access a certain address via web only for registration, check if that is your case.

I think the route table is right. The output of "show atm pvc 0/37":

Thank you very much Paolo,

That all seems fine. Can you ping the default gw ? If so, have you configure ip nat inside and globally with an ACL ?
06-18-2008 11:03 PM
Hi Paolo, I can't ping the default gateway. I have configured nat, but it was working well with the other connection. No ACL is configured. Any idea?
Best Regards.
06-19-2008 09:13 AM
Ok, try:
no interface BVI2
interface ATM0/3/0.1 point-to-point
no bridge-group 2
ip address A.B.C.D 255.255.255.252
ip nat inside source list 1 interface ATM0/3/0.1 overload
Replace ACL 1 with whatver number you've configured for NAT.
