Release Information
Statement introduced in Junos OS Release 9.0.
Description
Define a redundancy group. Except for redundancy group 0, a redundancy group is a logical interface consisting of two physical Ethernet interfaces, one on each chassis. One interface is active, and the other is on standby. When the active interface fails, the standby interface becomes active. The logical interface is called a redundant Ethernet interface (reth).
Redundancy group 0 consists of the two Routing Engines in the chassis cluster and controls which Routing Engine is primary. You must define redundancy group 0 in the chassis cluster configuration.
Options
group-number —Redundancy group identification number.
Range: 0 through 128
 | Note: The maximum number of redundancy groups is equal to the number of redundant Ethernet interfaces that you configure. |
