Set the Name field to supply an identification of the pair. This field initially defaults 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. Non-point to point interfaces such as Ethernet must be
configured with one. The Bring up backup link on demand option allows protocols such as DHCP
to be used to fetch an address when required.
