Configuring a VPLS Routing Instance

Like other Layer 2 VPNs, you must enable a routing instance to isolate VPLS traffic from other network traffic. To configure, include the instance-type vpls statement at the [edit routing-instances instance-name] hierarchy level.

Within the instance, you can define the maximum number of sites that can participate in this VPLS instance, the size of the MAC address table, a local site name, and a local site identifier.

To configure the maximum number of sites, include the site-range statement at the [edit routing-instances instance-name protocols vpls] hierarchy level. The maximum site range is 65,535.

Note: The site ID must be less than the site range. If you specify a site ID that is greater than the site range, your connections won't come up, even though the commit will be successful.

By default on MX-series routers, MAC statistics are disabled. To enable MAC statistics on MX-series routers, include the mac-statistics statement at the [edit routing-instances routing-instance-name instance-type vpls] hierarchy level.

To configure the size of the MAC address table, include the mac-table-size statement at the [edit routing-instances instance-name protocols vpls] hierarchy level. The default size is 5120 addresses, the minimum is 16 addresses, and the maximum is 65,536 addresses.

To configure a site name, include the site statement at the [edit routing-instances instance-name protocols vpls] hierarchy level. To configure the site ID, include the site-identifier statement at the [edit routing-instances instance-name protocols vpls site name] hierarchy level.
