  Origin IGP, metric 2165, **localpref 0**, weight 1000, valid, external
  Origin IGP, metric 2165, **localpref 0**, weight 1000, valid, external, bestpath-from-AS 6939, best (Weight)

---------------

** Inbound route-map applied to external routes, does not set local pref. All local pref for external routes is always 0 **

- [x ] Did you check if this is a duplicate issue? - seems others have had this issue in other versions
- [x ] Did you test it on the latest FRRouting/frr master branch? yes


**To Reproduce**
Add a route-map to external peers, set local pref to something, does not work. Setting weight works.

**Expected behavior**
expect route-map set localpref to work as expected.

**Versions**
- OS Version: Ubuntu 22.04
- Kernel: 6.2.0-1017-lowlatency
- FRR Version: FRRouting (version 9.1)
