The logic IP address, logic interface, and logic host name are configured. Ensure that the devices
that back up each other send the same information about NAS-IP-Address, NAS-Port, and
Option 82 contained in the packets to the RADIUS and DHCP servers.

11.4.4 (Optional) Setting the Interval for Backing Up Traffic or the
Traffic Threshold
If the intervals and traffic volume threshold are both set to 0, user traffic is not backed up.
Context
To ensure that the user traffic can be backed up in real time, do as follows on the devices that
back up each other:
Procedure
Step 1
Run:
system-view
The system view is displayed.
Step 2
Run:
remote-backup-profile
profile-name
The remote backup profile view is displayed.
Step 3
Run:
traffic backup
{
interval
interval-value
[
threshold
threshold-value
] |
threshold
threshold-value
[
interval
interval-value
] }
The interval for backing up traffic or the traffic threshold is set.

11.4.5 Configuring User Information Backup in Exclusive IP
Address Pool Mode
Configuring the exclusive address pool mode is easy and needs no additional links but wastes
IP addresses and does not support load balancing.
Context
If the exclusive IP address pool mode is adopted, you need to plan an address pool for each
physical interface and bind address pools to the RBP. When the RBP becomes the active device,
it advertises the address pool segment route. When the RBP becomes the standby device, the
address pool segment route is canceled. In this manner, the return route at the network side is
under control and the address pool segment route always leads to the active device. As a result,
the device can control the switching of user downstream forwarding paths through interfaces.
Perform the following steps on the devices that back up each other:
