Configuring the VPLS MAC Address Timeout
You can fine-tune your VPLS domain by clearing MAC address entries from the VPLS table or modifying the default timeout interval for the VPLS table.
On MX Series routers running Junos OS Release 8.4
and later, you can set the expiration time of entries in the MAC table
for the entire router, as opposed to for specific VPLS routing instances.
To set the expiration for the entire router, include the mac-table-aging-time
seconds statement at the [edit protocols l2-learning] hierarchy level. For instance level MAC agaging include the mac-table-aging-time statement at the [edit routing-instances
routing-instance-name protocols vpls] hierarchy level.
To clear all MAC address entries from the VPLS
table, issue the clear vpls mac-address command. Add the logical-system logical-system-name option
to clear entries within a logical system and include the instance instance-name option to clear entries in a specific
VPLS instance. Use the mac-address option to remove individual MAC addresses.
To configure the VPLS table timeout interval, include
the mac-table-aging-time statement at the [edit routing-instances instance-name protocols vpls] hierarchy level. The
default interval is 300 seconds, with a minimum of 10 seconds and
a maximum of 1 million seconds. As a general rule, you can configure
longer values for small, stable VPLS networks and shorter values for
large, dynamic VPLS networks. If no traffic is received for a specific
MAC address, M Series and T Series routers wait one additional
interval before automatically clearing MAC address entries from the
VPLS table. MX Series routers do not wait for this interval.
