Release Information

Statement introduced before JUNOS Release 7.4.

Description

Specify groups of objects that share characteristics resulting in backup paths to be used if primary paths fail. All objects are treated as /32 host addresses. You specify one or more objects within a group. The objects can be LAN interfaces, router IDs, or point-to-point links. The sequence is insignificant.

Options

cost value—Cost assigned to the group.
from address—Address of the router or address of the LAN/NBMA interface. For example, an Ethernet network with four hosts in the same fate-sharing group would require you to list all four of the separate from addresses in the group.
group group-name—Each fate-sharing group must have a name, which can have a maximum of 32 characters, including letters, numbers, periods (.), and hyphens (-). You can define up to 512 groups.
to address—(Optional) Address of egress router. For point-to-point link objects, you must specify both a from and a to address.
