Hello

Some points:

1) this should work as a way to change LOCAL_PREF

2) LOCAL_PREF is not shown in 'show route'. Use 'show route all' to show
LOCAL_PREF value. (100/5) values are different metrics - 100 is
'preference' (BIRD specific and BGP unrelated metric) and 5 is IGP metric
to the

3) bgp4_1_2_3 is iBGP? In that case you should not change LOCAL_PREF
(and most other BGP attributes) there. LOCAL_PREF is usually set on
import from eBGP. It is generally a bad idea to change route attributes
on iBGP links as that may easily lead to routing loops or oscillations.
