Hello.
In my test configuration of bird i want to announce two prefixes: [1]11.11.11.0/24 and [2]12.12.12.0/24.
But i do not understand how.
vlan3001 [3]11.11.11.1/28 (direct connected)
vlan3002 [4]11.11.11.17/28 (direct connected)
vlan3003 [5]11.11.11.65/26 (direct connected)
bird.conf
#v+
protocol static static_bgp {
route [6]11.11.11.128/25 via 11.11.11.66; route [7]12.12.12.0/24 via 11.11.11.66; }
protocol direct { interface "*"; }
#v-
This configration announce as is - two times /28, one /26 and one /25 of [8]11.11.11.0/24 prefix.
How to aggregate this in one /24 prefix in this sample?
Firstly, the term "announce" usually applies to BGP, but I cannot see anny configuration related to BGP. Secondly, every route being announced via BGP should be confirmed with some IGP protocol, for example, static. Thus if you have no 11.11.11.0/24 in IGP then 11.11.11.0/24 will not be announced via BGP. It seems you do not have 11.11.11.0/24 in IGP. Thirdly, if you want to announce only two /24 networks then make a outbound BGP filter and include them into it. -- MINO-RIPE
