6 PPP and MP configuration
Nortel Secure Router 8000 Series
Configuration -WAN Access
OQ NOTE
If one end adopts the authentication binding, while the other end adopts direct binding, perform the
previous configuration on the former. The later, which works as the authenticated, only needs to be
configured with MP direct binding through the VT. For details, see Configuring MP direct binding
Step 4 Choose one of the following methods to restart the interface.
•
Run the
shutdown and undo shutdown commands.
•
Run the
restart command.
When the interface is bound to the VT:
•
If LCP of the physical interface is in the Opened state, you must run the
shutdown and
undo shutdown commands or run the restart command on the physical interface to
restart the interface, so that the LCP negotiation is re-enabled to ensure that the physical
interface is successfully bound to the MP.
•
If the LCP negotiation on the physical interface fails and is still in the negotiation stage,
you need not restart the physical interface.
CD NOTE
To ensure that the physical interface is bound successfully to MP, Nortel recommends for you to restart
all the physical interfaces after all the bindings are configured.
—End
After running the
undo ppp mp command succeeds in the interface view, the MP binding is
deleted on the interface. At this time, you need not to restart the interface because the PPP
protocol can carry out auto-negotiation till the link layer status of the interface turns Up.
There are about 40 seconds from running the command to the Up status of the link layer
protocol.
6.7.4 Checking the configuration
Run the following commands to check the previous configuration.
Action
Command
