11.4.6 Configuring User Information Backup in Shared IP Address

The sharing address pool mode needs additional links but the networking is flexible.

If the exclusive IP address pool mode is adopted, a great number of address pools are needed.

This wastes addresses. The shared IP address pool mode addresses this problem. To adopt the

shared IP address pool mode, the following conditions must be met:

Perform the following steps on the devices that back up each other:

Issue 02 (2014-09-30)

Each remote backup profile can be bound to up to IP address pools of the entire device and the IP address

pools configured on the master and slave devices must be the same.

Address pools cannot be bound to the RBP.

Both the master and slave devices need to advertise the address pool segment route and be

configured with route policy. In this manner, the address pool segment route advertised by

the master device has a higher priority; load balancing is not performed on the router of the

network side.

A protection tunnel, for example, an LSP, needs to be set up between the master and slave

devices. When the uplink of the user fails, the downstream traffic of the user is introduced

to the protection tunnel.

The address pool is bound to the RBS, that is, the ip-pool pool-name command is used in

the RBS view. This ensures that traffic at the network side can be forwarded through the

protection tunnel before the host route is generated.

Only the primary address, not the secondary address pool, is bound to the RBS.

Configure the protection path in IP redirection mode for public users.
