Cisco 877 Config [Internode] [PPPoA]

Here is a sample 877 config for ISP Internode in Australia which I use. It may work with other providers as well, the only items you need to modify is the hostname, password sections, timezone, and possible your IP addressing/subnets etc

    It’s my understanding that aa5snap is used with PPPoE NOT PPoA, the configuration for PPPoA is as follows:

    interface ATM0
    description — Internode ADSL —
    no ip address
    no atm ilmi-keepalive
    pvc 8/35
    tx-ring-limit 3
    encapsulation aal5mux ppp dialer
    dialer pool-member 1

    dsl operating-mode auto
