After add comment next hop self and add gateway direct:
protocol static {
route 91.231.205.0/24 reject;
route 91.237.68.0/22 reject;
}
[..]
# next hop self;
gateway direct;
[..]
bird> show route 91.231.205.0/24 all
91.231.205.0/24 unreachable [static1 15:27] * (200)
Type: static unicast univ
via 91.231.205.193 on eth0 [bgp_syscom 15:27] (100)
[i]
Type: BGP unicast univ
BGP.origin: IGP
BGP.as_path:
BGP.next_hop: 91.231.205.193
BGP.local_pref: 100
Why static route is unreachable? On both routers are two prefixes in
static protocol. On second router is the same problem.
