    Hi all,

    delegating the first configuration to my colleagues and seeing the following:

    Current configuration : 173 bytes
    interface ATM0
    no ip address
    no atm ilmi-keepalive
    pvc 8/35
    ubr 160
    oam retry 5 5 1
    dialer pool-member 1
    protocol ppp dialer
    dsl operating-mode auto


    Current configuration : 275 bytes
    interface Dialer0
    ip address negotiated
    ip nat outside
    ip virtual-reassembly
    encapsulation ppp
    dialer pool 1
    ppp chap hostname XXXXXXXXXXXX
    ppp chap password 7 XXXXXXXXXXXXXXXx
    ppp pap sent-username XXXXXXXXXXXX password 7 XXXXXXXXXXXXXXXx

    I can not figure out which protrocol the router is using.

    How can I know it?
    As the router as no good performances before working on MTU and mss I would like to understand if it's using PPPOE or PPPOA.

    May any of you help me?

    This is I am pretty sure PPPoA.

    The Dialer is the same in both cases.


    pvc 8/35
    pppoe-client dial-pool-number 1

    R1#sh pppoe sess
    1 client session

    Uniq ID PPPoE RemMAC Port VT VA
    SID LocMAC VA-st
    N/A 2602 0090.1a71.1b20 ATM0/0 Di1 Vi1
    000f.f7f9.7a70 VC: 8/35 UP

    PPPoA bridging:
    interface ATM0.1 point-to-point
    bridge-group 1
    pvc 0/35
    encapsulation aal5snap

    N1#sh pppoe sess

    PPPoA routing:
    interface ATM0.1 point-to-point
    pvc 0/38
    encapsulation aal5mux ppp dialer
    dialer pool-member 1

    h#sh pppoe sess

    These are clearly only particular examples

  3. PPPoA.

    PPPoE would require some different config lines, and you'd see config
    lines with pppoe in them.
