Configuring a Pseudowire Subscriber Logical Interface Device
To configure a pseudowire logical interface device that the router uses for subscriber logical interfaces, you specify the logical tunnel that processes the pseudowire termination. You can also configure additional optional parameters for the interface device, such as VLAN tagging method, MTU, and gratuitous ARP support.
To configure the pseudowire subscriber interface device:
- Specify that you want to configure the pseudowire subscriber
logical interface device.user@host# edit interfaces ps0
- Specify the logical tunnel interface that is the anchor
point for the pseudowire logical interface device. The anchor point
must be an lt device in the format lt-fpc/pic/port. [edit interfaces ps0]user@host# set anchor-point lt-1/0/10
- (Optional) Specify the VLAN tagging method used for the
pseudowire logical interface device. You can specify single tagging,
dual (stacked) tagging, mixed (flexible) tagging, or no tagging. [edit interfaces ps0]user@host# set flexible-vlan-tagging
See Enabling VLAN Tagging for additional information about VLAN tagging.
- (Optional) Specify the MTU for the pseudowire logical
interface device. If you do not explicitly configure the MTU, the
router uses the default value of 1500.[edit interfaces ps0]user@host# set mtu 2500
See Setting the Protocol MTU for additional information.
- (Optional) Specify that the pseudowire logical interface
device does not respond to gratuitous ARP requests. [edit interfaces ps0]user@host# set no-gratuitous-arp-request
See Configuring Gratuitous ARP for additional information.
- Configure additional optional parameters for the pseudowire logical interface device, such as description, apply-groups, apply-groups-except, and traceoptions.
