MLPPP Contextual Command Differences

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.
