Description

Specify groups of objects which 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

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.

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.

to address—(Optional) Address of egress router. For point-to-point link objects, you must specify both a from and to address.
