On the router, for aggregated Ethernet interfaces only, configure link protection. In addition to enabling link protection, a primary and a secondary (backup) link must be configured to specify what links egress traffic should traverse. To configure primary and secondary links on the router, include the primary and backup statements at the [edit interfaces ge-fpc/pic/port gigether-options 802.3ad aex] hierarchy level or the [edit interfaces fe-fpc/pic/port fastether-options 802.3ad aex] hierarchy level.
On the switch, you can configure either Junos OS link protection for aggregated Ethernet interfaces or the LACP standards link protection for aggregated Ethernet interfaces.
For Junos OS link protection, specify link-protection at the following hierarchy levels:
[edit interfaces ge-fpc/pic/port ether-options 802.3ad aex]
[edit interfaces xe-fpc/pic/port ether-options 802.3ad aex] hierarchy level or at the [edit interfaces xe-fpc/pic/port ether-options 802.3ad aex] hierarchy level.
To disable link protection, use the delete interface ae aggregate-ether-options link-protection statement at the [edit interfaces aex aggregated-ether-options] hierarchy level or the [edit interfaces aex aggregated-ether-options lacp]] hierarchy level.
The remaining statements are explained separately. See CLI Explorer.
