Release Information

Statement introduced before Junos OS Release 7.4.

Statement introduced in Junos OS Release 9.0 for EX Series switches.

Statement introduced in Junos OS Release 11.3 for the QFX Series.

Description

Specify a backup path in case the primary path becomes unusable.

You specify one or more objects with common characteristics within a group. All objects are treated as /32 host addresses. The objects can be a LAN interface, a router ID, or a point-to-point link. Sequence is insignificant.

Changing the fate-sharing database does not affect existing established LSPs until the next CSPF reoptimization. The fate-sharing database does affect fast-reroute detour path computations.

Options

cost value—Cost assigned to the group.

Range: 1 through 65,535

Default: 1

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.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.
