LCP
The Link Control Protocol (LCP) is used to establish the connection through an exchange of
configure packets. This exchange is complete, and the LCP opened state entered, once a
Configure-Ack packet has been both sent and received.
LCP allows for the negotiation of multiple options in a PPP session. MLPPP is somewhat different
than PPP and therefore the following options are set for MLPPPP and not negotiated:
Any non-LCP packets received during this phase must be silently discarded.
Single-Fiber and Strip-Label
When configuring single-fiber and strip-label on the Ethernet port, the configured static MA
address must equal the MAC address of the next-hop router (mirrored port). When configuring
strip-label for both Ethernet and SONET/SDH ports, the IP address must be configured or the
interface will not come up.
