Description
Disable the ability to switch to a better priority link (if one is available) once a link is established as active and a collection or distribution is enabled.
(MX Series) By default, Link Aggregation Control
Protocol link protection is revertive. This means that after the current
link becomes active, the router switches to a higher-priority link
if one becomes operational or is added to the aggregated Ethernet
bundle. In a highly scaled configuration over aggregated Ethernet,
we recommend that you prevent the router from performing such a switch
by including the non-revertive statement. Failure to do
so may result in some traffic loss if a MIC on which a member interface
is located reboots. Using the non-revertive statement for
this purpose is not effective if both the primary and secondary interfaces
are on the MIC that reboots.
Required Privilege Level
