For a provider-edge (PE) router with customer edge (CE)-facing, egress, ATM2 IQ interfaces configured with standard AAL5 encapsulation, you can enable the PLP setting to be copied into the CLP bit.
Note: This configuration setting is not applicable to Layer 2 circuit encapsulations because the control word captures and preserves CLP information. For more information about Layer 2 circuit encapsulations, see the JUNOS Network Interfaces Configuration Guide.
By default, at egress ATM2 IQ interfaces configured with standard AAL5 encapsulation, the PLP information is not copied to the CLP bit. This means the PLP information is not carried beyond the egress interface onto the CE router.
You can enable the PLP information to be copied into the CLP bit by including the plp-to-clp statement:
You can include this statement at the following hierarchy levels:
