Configuring the VPLS MAC Table Timeout Interval

Configuring the Size of the VPLS MAC Address Table

You can modify the timeout interval for the VPLS table. We recommend you that configure
longer values for small, stable VPLS networks and shorter values for large, dynamic VPLS
networks. If the VPLS table does not receive any updates during the timeout interval, the
router waits one additional interval before automatically clearing the MAC address entries
from the VPLS table.
To modify the timeout interval for the VPLS table, include the
statement:
mac-table-aging-time seconds;
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]

You can modify the size of the VPLS media access control (MAC) address table. The
default table size is 512 MAC addresses, the minimum is 16 addresses, and the maximum
is 65,536 addresses.
NOTE: T4000 routers with Type 5 FPCs support up to 262,143 MAC addresses
per VPLS routing instance. To enable the improved VPLS MAC address
learning limit (that is, 262,143 MAC addresses), you must Include the

level, reboot the router, and then modify the size of the VPLS MAC address
table.
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.
To change the VPLS MAC table size for each VPLS or VPN routing instance, include the
statement:
