Hierarchy Level


For MX Series routers with multichassis aggregated Ethernet (MC-AE) interfaces, you can use this statement under the physical interface level to reduce the configuration at the logical interface level if the following assumption exists:

If there are n +1 logical interfaces under ae0, from ae0.0 through ae0.n, there will be n + 1 logical interfaces under ge-0/0/0 as well, from ge-0/0/0.0 through ge-0/0/0.n, and each ge-0/0/0 logical interface will be a protection link for the ae0 logical interface.


A bridge domain cannot have MC-AE logical interfaces which belong to different redundancy groups.

If the Inter-Chassis Control Protocol (ICCP) connection is UP and the interchassis data link (ICL) comes UP, the router configured as standby will bring up the MC-AE interfaces shared with the peer.

The remaining statements are explained separately. See CLI Explorer.
