Disable the Removal of Address and Control Bytes
For PPP CCC-encapsulated interfaces, the address and control bytes are removed by default before the packet is encapsulated into a tunnel.
You can disable the removal of address and control bytes. To do this, include the
keep-address-and-controlstatement:keep-address-and-control;You can configure this statement at the following hierarchy levels:
[edit interfacesinterface-nameunitlogical-unit-numberfamilyccc]- [
edit logical-routerslogical-router-nameinterfacesinterface-nameunitlogical-unit-numberfamilyccc]When you use PPP CCC encapsulation, and one PE router is running JUNOS software Release 5.7 or earlier and the other PE router is running JUNOS software Release 6.0 or later, you must include the
keep-address-and-controlstatement in the configuration of the PE router running JUNOS software Release 6.0 or later.
