The MLPPP configuration commands have different effects depending on the interface
context. If you issue an MLPPP configuration command in the context of an individual
interface, the command affects only the MLPPP link interface associated with that
individual interface.
For example, the following commands disable negotiation of the local magic number
only for serial interface 2/0:1/1.
host1(config-if)#member-interface serial 2/0:1/1
host1(config-if)#encapsulation mlppp
host1(config-if)#ppp magic-number disable
If you issue an MLPPP configuration command in the context of an MLPPP bundle—the
MLPPP network interface—the command affects all the member links of the bundle.
This feature prevents you from having to issue MLPPP configuration commands for each
member link interface.
For example, the following commands disable negotiation of the local magic number
for the entire bundle, group1.
host1(config)#interface mlppp group1
host1(config-if)#member-interface serial 2/0:1/1
host1(config-if)#ip address 10.10.100.1 255.255.255.0
host1(config-if)#ppp magic-number disable
Any member links added to the bundle after issuing an MLPPP configuration command
are not affected by the command. For example, if you add serial interface 2/0:4/1 to the
group1 bundle after you issue the ppp magic-number disable command, negotiation of
the local magic number for this link and any member links subsequently added to the
bundle is not disabled.
Perform the following optional tasks to configure authentication on interfaces with
MLPPP encapsulation or MLPPP bundles.
Specify one or more PPP authentication types.
