fate-sharing

Syntax

Hierarchy Level

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.
