You can include this statement at the following hierarchy levels:

•

[edit routing-instances routing-instance-name protocols vpls]

•

[edit logical-systems logical-system-name routing-instances routing-instance-name

protocols vpls]

NOTE: ACX Series routers do not support the [edit logical-systems] hierarchy.

When you include the mac-table-size statement, the affected interfaces include all

interfaces within the VPLS routing instance, including the local interfaces, the LSI

interfaces, and the VT interfaces.

NOTE: ACX Series routers do no support mac-table-size statement for VPLS.

Limiting the Number of MAC Addresses Learned from an Interface

You can configure a limit on the number of MAC addresses learned by a VPLS routing

instance using the mac-table-size statement. If the MAC table limit is reached, new MAC

addresses can no longer be added to the table. Eventually the oldest MAC addresses are

removed from the MAC address table automatically. This frees space in the table, allowing

new entries to be added. However, as long as the table is full, new MAC addresses are

dropped.

Because this limit applies to each VPLS routing instance, the MAC addresses of a single

interface can consume all the available space in the table, preventing the routing instance

from acquiring addresses from other interfaces.

You can limit the number of MAC addresses learned from each interface configured for

a VPLS routing instance. To do so, include the interface-mac-limit statement:

interface-mac-limit limit;

NOTE: ACX Series routers do not support interface-mac-limit limit for VPLS.

You can include this statement at the following hierarchy levels:

•

[edit routing-instances routing-instance-name protocols vpls]

•

[edit logical-systems logical-system-name routing-instances routing-instance-name

protocols vpls]

The interface-mac-limit statement affects the local interfaces only (the interfaces facing

CE devices).

Configuring the interface-mac-limit statement at the [edit routing-instances

routing-instance-name protocols vpls] hierarchy level causes the same limit to be applied

to all of the interfaces configured for that specific routing instance.
