Configuring Shared Interfaces on a PSD

To configure shared interfaces on a PSD:

Configure the physical SONET interface with Frame Relay encapsulation using the so-fpc/pic/slot statement at the [edit interfaces] hierarchy level.
Identify the physical SONET interface as a shared interface using the shared-interface statement at the [edit interfaces so-fpc/pic/slot] hierarchy level.
Configure logical SONET interfaces under the physical interface using the unit logical-unit-number statement at the [edit interfaces so-fpc/pic/slot] hierarchy level. The values for logical-unit-number must match the values set in the RSD configuration.
For each logical SONET interface, include the following statements at the [edit interfaces so-fpc/pic/slot unit logical-unit-number] hierarchy level:
1. dlci dlci-identifier—Assign a data-link connection identifier (DLCI) for the point-to-point Frame Relay connection between the RSD and the PSD. The value for dlci-identifier must match the value set in the RSD configuration for the specified logical SONET interface.
2. peer-interface interface-name—Configure the logical tunnel peer interface that is bound to the logical SONET interface.
3. family family—Configure the protocol family for the logical SONET interface.
Configure the IP address of the logical SONET interface using the address address statement at the [edit interfaces so-fpc/pic/slot unit logical-unit-number family family] hierarchy level.
Configure the physical tunnel interface using the ut-fpc/pic/slot statement at the [edit interfaces] hierarchy level.
Configure the logical tunnel interfaces using the unit logical-unit-number statement at the [ut-fpc/pic/slot] hierarchy level.
For each logical tunnel interface, specify the logical peer interface on the SONET PIC using the peer-interface statement at the [ut-fpc/pic/slot unit logical-unit-number] hierarchy level.

PSD1

In the following example, the logical SONET interface so-0/0/0.0 is peered with the logical tunnel interface ut-1/0/0.0 and so-0/0/0.1 is peered with ut-1/0/0/.1.



interfaces {


so-0/0/0 {
encapsulation frame-relay;
shared-interface;


unit 0 {
dlci 100;
peer-interface ut-1/0/0.0;


family inet {
address 10.10.10.1/24;
}


}




unit 1 {
dlci 101;
peer-interface ut-1/0/0.1


family inet {
address 10.10.11.1/24;
}


}


}




ut-1/0/0 {


unit 0 {
peer-interface so-0/0/0.0;
}




unit 1 {
peer-interface so-0/0/0.1;
}


}


}

PSD2

In the following example, the logical SONET interface so-0/0/0.2 is peered with the logical tunnel interface ut-2/0/0.2.



interfaces {


so-0/0/0 {
encapsulation frame-relay;
shared-interface;


unit 2 {
dlci 102;
peer-interface ut-2/0/0.2;


family inet {
address 10.10.12.1/24;
}


}






ut-2/0/0 {


unit 0 {
peer-interface so-0/0/0.2;
}


}


}
