Hello

In BIRD 1.6 when a non-BGP route is exported to BGP, core BGP attributes
(like bgp_local_pref, bgp_path and some others) are initialized
regardless of their previous value. So if you want to sed bgp_local_pref,
you have to do it BGP export filter.

Or switch to BIRD 2.0, where this behavior was changed and and only
undefined attributes are initialized when route is exported to BGP.
