Caution:
If the command is enabled, the amount of resources required is twice the amount required
without uniform FRR, and the number of LDP-over-RSVP LSPs that can be accommodated in the
MPLS FIB is therefore halved if uniform FRR is enabled. Ensure that sufficient MPLS resources
are available to accommodate all required LDP-over-RSVP LSPs before using this command.
The no form of this command disables the use of uniform FRR for LDP-over-RSVP LSPs.

Description
This command configures the G.8032 fast-flood feature. When this command is executed, it is stored in
the configuration file after admin save is executed. A system reboot is required for this command to take
effect.
Nokia recommends enabling this command to improve service failover time due to failures in the ring path.
When fast flood is enabled, on failure detection in one of the paths of the ETH-ring, along with MAC flush,
the system starts to flood the traffic on-to the available path.
If this command is present in the configuration file, on reboot, the system allocates resources for G.8032,
by reducing the amount of resources available for use with ACLs. When this command is used, G.8032
fastflood needs an entire chunk with ‟512” entries, therefore the amount of resources available for use with
ACLs is reduced by ‟512”. The user needs to free up resources used by ACLs and make them available for
use by G.8032, before enabling this command. The user should ensure that the resource usage of ACLs
has been appropriately modified before reboot, to make way for use of this feature. The user can free up
resources by either disabling the use of ACLs with a SAP or deleting a SAP, so that an entire chunk of 512
entries is available.
Before enabling the g8032-fast-flood-enable command, the user must check if sufficient resources are
available. The tools dump system-resources command is available to check if sufficient resources
are available. The 'Ingress Shared CAM Entries' field, shown in the output below tools dump system
resources command, must be more than or equal to 512 (the ‛Free’ column in the following output).
| Total | Allocated | Free
