Thanks for the answer.

What happens when the preference is the same for two different protocol
types - which protocol is preferred? For example, if you have the
preference of BGP and Babel routes both set to 100, which route will be
chosen? BGP and Babel routes can't really be compared since BGP takes
the AS path and Babel takes the metric as the main decision criterion.

Is it possible to view the preference using "birdc"?    

 `birdc show route` shows the protocol preference at the end of the line
 in brackets. Or do you mean something different, like when showing the
 protocols?  

```
                     unicast [brandweb_v4 17:31:34.208] (100)
                     [AS4242422032i] via 172.20.191.129 on brandweb
```
So that would have a preference of 100, right?  

Yes.


```
fd04:234e:fc31::/128 unicast [inner_network 2023-06-13] (130/1)
[00:00:00:00:ac:16:95:e2] via fe80::2923:1 on p2prouter
```
And what would be the preference 130 with a Babel metric of 1?
  

Yes. 130 is the default preference for babel.

`show protocols all`, does show the preference, too.  

Where exactly? I could not find anything there.
  

```
# birdc show protocols all
# Shows all configured protocols, their state, details, etc, including
preference.

# To view a single protocol:
# birdc show protocols all ospf_ipv6
BIRD 2.0.8 ready.
