Release Information

Statement introduced in Junos OS Release 11.1.


For MX Series routers with multichassis aggregated Ethernet (MC-AE) interfaces, use the multi-chassis-protection statement under the physical interface level to reduce the configuration at the logical interface level. If the interchassis control protocol connection (ICCP) 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 active-active node specified by the peer statement. You must also specify the peer’s physical interface.


a.b.c.dSpecify the IP address of the peer.
interface interface-nameSpecify the peer’s physical interface: interface interface-name-fpc/pic/port
