    Configuring the Router to Ignore a Mismatch of the Peer Magic Number

    You can optionally configure the router to ignore a mismatch of the Link Control Protocol (LCP) peer magic number and retain the PPP connection when the peer has not negotiated an LCP magic number. You can configure the router to ignore a mismatch from the Interface Configuration Mode, the Subinterface Configuration mode, and the Profile Configuration mode.

    To configure the router to ignore a mismatch of the peer magic number:

    • (Optional) From the Interface Configuration mode, specify the following command:
      host1(config-if)#ppp magic-number ignore-mismatch

      Use the no version to restore the default behavior, in which the router terminates the PPP connection if it detects an LCP peer magic number mismatch.
