>From the Cisco docs:

 

RFC 1483 Bridging Implementations 

Select one of these RFC 1483 bridging implementations for your Asymmetric
Digital Subscriber Line (ADSL) service. 

*	Integrated
<http://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_examp
le09186a008071a5d0.shtml>  Routing and Bridging (IRB) -(Recommended) The IRB
feature allows your Cisco DSL Router to bridge traffic in on its ATM
interface (the ADSL interface) and then route that traffic out on its
Ethernet interface. With IRB enabled, the Cisco DSL Router can perform
value-added services such as Network Address Translation (NAT) overload, NAT
Pool, Static NAT, and Dynamic Host Control Protocol (DHCP) Server. 
*	Pure
<http://www.cisco.com/en/US/tech/tk175/tk15/technologies_configuration_examp
le09186a008071a88e.shtml>  Bridging -In a Pure Bridging implementation, your
Cisco DSL Router acts as a simple ADSL to Ethernet bridge, and is unable to
provide value-added services. 

I think you want to do IRB..

 

Here's an example:

My ISP connect to by PA-A6-OC3SMI, and it tell me an ATM PVC to every
cutomer, so I can use PPPoA

 

Now I think to start is most friendly use RFC1483, but I don't know if I
could use routed or bridge....???

 

in my country the most big telco use RFC1483 but I don't see never our side
but only customer site and I configure connction using this:

 

interface ATM0
 no ip address
 no atm ilmi-keepalive
 dsl operating-mode auto 
!
interface ATM0.1 point-to-point
 bandwidth 2048
 ip address XXX.XXX.XXX.XXX 255.255.255.252
 pvc 8/35 
  oam-pvc manage
  oam retry 5 5 1
  encapsulation aal5snap
 !

 

Now I would configure my customer with this example but I don't configure
never other side..... can you send me some example ??

This is is RFC1483 routed or bridge ??

 

Thank you

 

Mat
