LCP. Link Control Protocol. Protocol responsible for negotiating connection
configuration parameters, authenticating peers on the link, determining
whether a link is functioning properly, and terminating the link. Documented

magic number. Random number generated by a router and included in
packets it sends to other routers. If the router receives a packet with the
same magic number it is using, the router sends and receives packets with
new random numbers to determine if it is talking to itself.
MD5. A 128-bit, message-digest, authentication algorithm used to create
digital signatures. It computes a secure, irreversible, cr yptographically
strong hash value for a document. Less secure than variant SHA-1.
metric. Distance, measured in the number of routers a packet must
traverse, that a packet must travel to go from a router to a remote network.
A route with a low metric is considered more efficient, and therefore prefera-
ble, to a route with a high metric. See hop count.
modem. Modulator/demodulator. Device used to convert a digital signal to
an analog signal for transmission over standard telephone lines. A modem
