"Encapsulation failed" when trying to send on VPDN interface.

Discussion in 'Cisco' started by Yehavi Bourvine, Aug 1, 2004.

  1. Hello,

    I have a Cisco-3,640 running 12.2(19) serving as an LNS server for people who
    use VPDN dialler to connect to it (it has two legs, one on a private network
    over which people use the Microsoft VPN dialler to authenticate).

    All is working ok until people start having communication problems; the VPDN
    connect and then nothing... Using DEBUG IP PACKET DETAIL I've found that the
    packet cannot be sent from the Cisco because of "encapsulation failed"; the
    routing seems ok, and ping to the private address is ok also. A reboot fixes

    Any idea how to look for the source of this "encapsulation failed" error?

    Thanks! __Yehavi:
