Thanks for providing that. I was thinking about the same but couldn't find it in the manual. Additional question is do I see it correctly that bird in comparison to Cisco/Juniper does reverse logical so higher value means "more preferred" route?

Regards,
Grzegorz

Hello!
I could not find any information about default protocol preference values
(administrative distance) for bird. Can anybody please help with it? Are
there any default values for OSFP, BGP, static, etc.? Or is it better to
configure each value explicitly?

Hello

#define DEF_PREF_DIRECT                           240         /* Directly connected */
#define DEF_PREF_STATIC                            200         /* Static route */
#define DEF_PREF_OSPF                               150         /* OSPF */
#define DEF_PREF_BABEL                             130         /* Babel */
#define DEF_PREF_RIP                   120         /* RIP */
#define DEF_PREF_BGP                 100         /* BGP */
#define DEF_PREF_RPKI                 100         /* RPKI */
#define DEF_PREF_INHERITED    10           /* Routes inherited from other routing daemons */
