Hierarchy Level


For MX Series routers, the configuration statement is supported at the [bridge-options], [protocols vpls], and [protocols evpn] hierarchy levels only.


Modify the timeout interval for the MAC table.

For MX Series routers, you can use the global-mac-table-aging-time statement at the [edit protocols l2-learning] hierarchy level to configure the timeout interval at the global level or use the mac-table-aging-time to configure the timeout interval for a bridge domain or for a specific VPLS or EVPN instance. If multiple timeout interval values are configured on a router, the router determines the timeout interval value in the following order of priority:

  • Timeout interval configured at the VPLS or EVPN instance

  • Timeout interval configured for the bridge domain

  • Global timeout interval configured on the router


For MX Series routers, the timeout interval configuration feature is supported on routers with MPCs only.
