Chapter 8 - The E1 and T1 Interfaces, With Signaling

Cyclades-PR4000

Configuration of Multilink PPP (with an extension to Multichassis Multilink PPP) includes the following steps:

STEP ONE
The first four parameters in the PPP Menu must be defined. The PPP Menu can be reached by following the path:
CONFIG =>INTERFACE =>

<INTERFACE or LINK> =>ENCAPSULATION =>PPP. The first parameter enables

MLPPP. The second parameter determines the type of connection (leased line, dial-in, etc.). The third parameter
is the number assigned to the bundle, as described above (except for dial-in lines, where the bundle is defined
dynamically). The number itself is not important, but must be consistently used by the routers on both ends of the
connection. The fourth parameter determines the maximum number of links included in the multilink PPP circuit.

STEP TWO (only for Multichassis Multilink PPP)
The menu CONFIG =>IP =>MCPPP contains the only two parameters necessary to enable MCPPP. The first is
the MCPPP End Point Discriminator, which must be the same for all RASs that will participate in the Multichassis
Multilink PPP Circuit. The value of the number is immaterial, but it must have the form of a MAC number, as
shown in the example. The other parameter is the MCPPP IP Address, which must be the same as the Ethernet
IP address for the LAN where the other RASs are located. The MCPPP parameters must be set for all the RASs
that will participate in the circuit.

The Network Protocol Menu tree is explained in chapter 9. The only routing protocol available is RIP. RIP is
described in chapter 11. For each channel, certain signaling parameters must be configured. This menu tree is
shown in Figure 8.9.
