Parameters
additional-path-always: Allows the indirect suboptimal route as the backup route.
Usage guidelines
Prefix Independent Convergence (PIC) enables the device to speed up network convergence by ignoring
the number of prefixes.
When both IS-IS PIC and IS-IS FRR are configured, only IS-IS FRR takes effect.
Examples
# Configure IS-IS PIC to support the indirect suboptimal route as the backup route.
<Sysname> system-view

Parameters
preference: Specifies an IS-IS protocol preference in the range of 1 to 255.
route-policy route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63
characters, to assign a priority to the matching routes.
Usage guidelines
If a routing policy is specified in this command, the preference set by the routing policy applies to the
matching routes. Other routes use the preference set by the preference command.
If multiple routing protocols find routes to the same destination, the route found by the routing protocol
with the highest preference is selected as the optimal route.
