11.5.5 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 active and standby 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 active 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 active and standby
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
[
metric
metric-
num
] or
ipv6-pool
pool-name
[
metric
metric-value
] 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.
To configure the protection path in IP redirection mode, you need to deploy the directly
connected link between the devices that back up each other.
