Configuring L2TPv3 on Cisco Devices

    Hi all

    I'm trying to configure an L2TPv3 tunnel on two Cisco 7200 VXR running
    IOS 12.0(31)S. My goal is to tunnel ethernet frames over an IP cloud
    using the xconnect service.

    However I get strange error messages telling me some configs being
    incomplete. Even if I type in the configuration example Cisco provides
    I don't get the whole thing running.

    This is the Cisco example:
    ********************
    l2tp-class l2tp-defaults
    retransmit initial retries 30
    cookie-size 8

    pseudowire-class ether-pw
    encapsulation l2tpv3
    protocol none
    ip local interface Loopback0

    interface Ethernet 0/0
    xconnect 10.0.3.201 123 encapsulation l2tpv3 manual pw-class ether-pw
    l2tp id 222 111
    l2tp cookie local 4 54321
    l2tp cookie remote 4 12345
    l2tp hello l2tp-defaults

    This is what I have typed:
    **************************
    l2tp-class l2tp-defaults
    retransmit initial retries 30
    cookie size 8

    pseudowire-class ether-pw
    encapsulation l2tpv3
    protocol none
    ip local interface Loopback0

    Left_Router(config)#int f1/1
    Left_Router(config-if)#xc 192.168.1.2 123 enc l2tpv3 man pw-class
    ether-pw
    Left_Router(config-if-xconn)#l2tp id 1 2
    Left_Router(config-if-xconn)#l2tp cookie local 4 54321
    Left_Router(config-if-xconn)#l2 coo rem 4 12345
    Left_Router(config-if-xconn)#l2tp hello l2tp-defaults
    Left_Router(config-if-xconn)#exit

    This is what the router tells me on exit:
    *****************************************
    Xconnect configuration on this circuit is incomplete
    Left_Router(config-if)#

    And this is what's in the config afterwards: (only interface part)
    ********************************************
    interface FastEthernet1/1
    ip address 192.168.100.1 255.255.255.0
    no ip directed-broadcast
    duplex full
    speed 100
    xconnect 192.168.1.2 123 encapsulation l2tpv3 manual pw-class ether-pw
    l2tp id 1 2
    l2tp cookie local 4 54321
    l2tp cookie remote 4 12345
    l2tp hello l2tp-defaults
    match protocol ipv6

    >>> Does anybody know what I'm doing wrong and where the hell the

    router takes the IPv6 command and if it's even possible to run L2TPv3
    over IP? Keep in mind that Cisco is providing L2TPv3 quite a long time,
    the RFC 3931 exists since March 2005.

    Thanks a lot in advance for your help!!
