The `ip` command is capable of adding routes to the table that simultaneously define the next-hop and interface.
The current `set protocols static route`, `set protocols static interface-route` , and their respective IPv6 sister commands do not reflect this capability. Attempting to use both of these command sets at once causes weird routing table entries, while `ip` works as expected.
I suggest the following syntax:
```
set protocols static route <CIDR> next-hop <ADDR>/blackhole
set protocols static route <CIDR> interface <DEV>
set protocols static route <CIDR> distance <1-255>
set protocols static route <CIDR> dhcp-interface
set protocols static route <CIDR> disable
```
or
```
set protocols static route <CIDR> next-hop <ADDR>
set protocols static route <CIDR> interface <DEV>
set protocols static route <CIDR> distance <1-255>
set protocols static route <CIDR> dhcp-interface
set protocols static route <CIDR> status blackhole
set protocols static route <CIDR> status disable
```
With any necessary changes also made to the ipv6 command variants.
I'm not familiar enough with the code base to tell if this is actually a limitation of Quagga or not.
