I do not know if this is as intended or a bug.
While playing with a local BGP setup I encountered the following symptome:
#R1 AS65000
```
vyos@vyos# show interfaces ethernet eth0 vif 666
address 2001:db8:1::1/64
```
```
vyos@vyos# show protocols bgp

}

}
}
neighbor 2001:db8:1::2 {
remote-as 65001
}
parameters {
log-neighbor-changes
router-id 172.18.254.202
}
}
```
```
vyos@vyos# show protocols static route
route 10.0.0.0/9 {

}
route 10.128.0.0/9 {
blackhole {
}
}
```
```
vyos@vyos# vtysh -c "show run"
