Hi ,
Bird support  the configuration of  efault bgp_local_pref. In export filter, this attribute can also be reconfigure.

default bgp_local_pref number
A default value for the Local Preference attribute. It is used when a new Local Preference attribute is attached to a route by the BGP protocol itself (for example, if a route is received through eBGP and therefore does not have such attribute). Default: 100 (0 in pre-1.2.0 versions of BIRD).
Thanks

Hi  All,
    According to RFC1930, the AS number 64512 to 65535  are reserved for private,  I cannot find the implementation for  checking  private AS number in BIRD, anybody know it or it’s lost in BGP ?

RFC1930
10<https://tools.ietf.org/html/rfc1930.html#section-10>. Reserved AS Numbers





   The Internet Assigned Numbers Authority (IANA) has reserved the

   following block of AS numbers for private use (not to be advertised

   on the global Internet):



                           64512 through 65535

Thanks
Arvin
