2.2.5 Configuring the Warmup Timer

Normally, when a router enabled with dial-up backup reboots, it may bring up the
backup dial-up link if the negotiation of the main link is too slow; after the main link goes
up, the traffic is switched to the main link.
After a warmup timer is set, the router tries to dial the backup link only when the main
link fails to come up upon timeout of the warm-up timer.
Perform the following configuration in system view.

By default, the warmup timer is set to 30 seconds.

2.2.6 Configuring Backup Load Sharing

Before you can use this command, you must configure the standby interface
command.
Perform the following configuration in the view of the main interface.
Table 2-6 Configure load sharing on the main interface
Configure backup load sharing on the
main interface.
Disable backup load sharing on the main
interface.
By default, backup load sharing is disabled on the interface.

2.2.7 Setting Backup Bandwidth of the Main Interface

When the main interface participates in backup load sharing, the backup center uses
the backup bandwidth that you configured preferentially. If it is not configured, the
backup center automatically obtains the backup bandwidth that the system assigns to
the main interface, and if it is not available, requires you to assign backup bandwidth to
the main interface.
Before you can use this command, you must configure the standby interface
command.
Perform the following configuration in the view of the main interface.
