Configuring the Service Logical Interface for a Pseudowire Subscriber Logical Interface
This topic describes how to configure a pseudowire service logical interface. Service logical interfaces represent the attachment circuits for pseudowire logical interfaces.
As described in the Pseudowire Subscriber Logical Interfaces Overview, you can choose whether to configure a service logical interface together with a higher subscriber logical interface, depending upon the business need. In a broadband edge configuration, the higher subscriber logical interface is the demarcation point for subscribers. However, in a business edge configuration, the service logical interface is the demarcation point for the business subscribers, and also serves as the subscriber logical interface, so no subscriber logical interfaces are explicitly configured.
 | Note: Non-zero unit numbers represent service logical interfaces used for pseudowire subscriber interfaces. Use unit 0 to represent the transport logical interface for the pseudowire device. |
To configure a pseudowire service logical interface:
- Specify that you want to configure the pseudowire subscriber
logical interface device.[edit]user@host# edit interfaces ps0
- Configure the unit for the service logical interface.
Use a non-zero unit number.[edit interfaces ps0]user@host# edit unit 1
- Configure the VLAN tag IDs. [edit interfaces ps0 unit 1]user@host# set vlan-tags outer 1 inner 1
- Configure the interface to respond to ARP requests when
the device has an active route to the ARP request target address.[edit interfaces ps0 unit 1]user@host# set proxy-arp
- Specify that you want to configure the protocol family
information. Pseudowire service logical interfaces support IPv4 (inet),
IPv6 (inet6), and PPPoE (pppoe) protocol families.
For example, to configure the IPv4 family:
- Specify that you want to configure IPv4.[edit interfaces ps0 unit 1]user@host# edit family inet
- Configure the parameters for the family.[edit interfaces ps0 unit 1 family inet]user@host# set filter input filter 1 output filter 4user@host# set mac-validate looseuser@host# set input-hierarchical-policer policer-1user@host# set unnumbered-address lo0.0 preferred-source-address 100.0.0.1
- Specify that you want to configure IPv4.
