Chapter 4 Edit Interface/Connection
Backup Configuration
Next Hop Forwarding
These fields are optional. You can enter the IP address to which the primary and
backup interfaces will connect when they are active. This is known as the next hop
IP address. If you do not enter next hop IP addresses, SDM will configure static
routes using the interface name. Note that in the case where you are backing up a
multipoint WAN connection, such as an Ethernet connection, you must enter next
hop IP addresses in order for routing to occur properly, but when backing up a
point-to-point connection, this information is not necessary.
Primary Next Hop IP Address
Enter the next hop IP address of the primary interface.
Backup Next Hop IP Address
Enter the next hop IP address of the ISDN BRI or analog modem backup interface.
