MPLS/VPN Support
How to Display the Name of the Subscriber Mapped to a Specified VPN
If the MPLS/VPN is configured as a single subscriber mapped to 0.0.0.0/0 on the VPN that is mapped
to the specified MPLS, this option displays that subscriber
Note
This command provides backward compatibility for MPLS/VPN subscriber configuration in SCOS
versions previous to 3.1.5.
Step 1
From the SCE> prompt, type show interface linecard 0 subscriber mapping MPLS-VPN PE-ID pe-id
BGP-label label and press Enter.

Displaying the Subscriber Mapped to a Specified VPN: Example 1
SCE>show interface lineCard 0 subscriber mapping MPLS-VPN PE-ID 1.0.0.1 BGP-label 30
BGP MPLS label 30 on PE 1.0.0.1 is mapped to VPN named 'Vpn1'
The VPN is NOT mapped to a single subscriber (0.0.0.0/0@Vpn1)
Displaying the Subscriber Mapped to a Specified VPN: Example 2
SCE>show interface lineCard 0 subscriber mapping MPLS-VPN PE-ID 1.0.0.1 BGP-label 30
BGP MPLS label 30 on PE 1.0.0.1 is mapped to VPN named 'Vpn1'
Subscriber 'Sub10' is mapped to 0.0.0.0/0@Vpn1
How to Display the Mappings of Upstream Labels that Belong to Non-VPN Flows
From the SCE> prompt, type show interface linecard 0 MPLS-VPN non-VPN-mappings and press
Step 1
Enter.
Clearing Upstream VPN Mappings
Use this command to remove all learned upstream labels of a specified VPN.
Options
The following option is available:
•
Step 1
From the SCE# prompt, type clear interface linecard 0 VPN name vpn-name upstream mpls all and
press Enter.
This command, in effect, causes early label aging. Clearing the mappings allows relearning; labels will
probably be quickly relearned after they have been cleared. Therefore, this command is useful when you
want to update the VPN mappings without waiting for the standard aging period.
