to the “main_link_name->backup_link_name”.
The Enable this configuration field enables this backup.
The Transfer default gateway field causes the gateway to be transferred to the
backup link upon failure of the main link path. If the backup interface is point to
point, such as PPP, the Backup gateway IP address can be automatically determined.

Bring up backup link on demand option allows protocols such as DHCP to be used
to fetch an address when required.
