Verifying Your Work

To verify proper operation of VPLS, use the following commands:

clear vpls mac-address instance instance-name
show interfaces terse
show route forwarding-table family mpls
show route forwarding-table family vpls (destination | extensive | matching | table)
show route instance (detail)
show system statistics vpls
show vpls connections
show vpls statistics

The following section shows the output of these commands on Router PE1 as a result of the configuration example:

To display VPLS source and destination MAC address accounting information, use the destination, extensive, matching, or table option with the show route forwarding-table family vpls command. When you analyze the display output, keep in mind the following:

VPLS MAC address accounting is handled on a per-MAC address basis for each VPLS instance. All information is retrieved from MAC address entries in the MAC address table. VPLS MAC address accounting is performed only on local CE routers.

The VPLS counters for source and destination MAC addresses increment continuously until the oldest MAC address entries are removed from the memory buffer, either when the entries time out or if the VPLS instance is restarted.

To clear all MAC address entries for a VPLS instance from the VPLS table, issue the clear vpls mac-address instance instance-name command. Add the logical-system logical-system-name option to clear entries in a VPLS instance within a logical system. Use the mac-address option to remove individual MAC addresses.
