Preventing validation of magic numbers in PPP peer-originated keepalive messages

You can include the ignore-magic-number-mismatch statement to disable the Packet Forwarding Engine from validating PPP magic numbers received during PPP keepalive (Echo-Request/Echo-Reply) exchanges. Because validation is not performed, the Packet Forwarding Engine does not detect whether the remote peer sends a magic number that does not match the number agreed upon during LCP negotiation. This prevents PPP from tearing down the session in the event of a mismatch. This capability is useful when the remote PPP peers include arbitrary magic numbers in the keepalive packets. Configuring this statement has no effect on LCP magic number negotiation or on the exchange of keepalives when the remote peer magic number is the expected negotiated number.
