Step 3
Run:
ip-pool

11.4.6 Configuring User Information Backup in Shared IP Address
Pool Mode
The sharing address pool mode needs additional links but the networking is flexible.
Context
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:
l
Address pools cannot be bound to the RBP.
l
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.
l
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.
l
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.
NOTE
Only the primary address, not the secondary address pool, is bound to the RBS.
Perform the following steps on the devices that back up each other:
Procedure
l
Configure the protection path in IP redirection mode for public users.
