Please could you explain the reason for this change, I don't see a src node in the YANG module?

Nevermind, I see your danos/vyatta-protocols-common#1 PR now! :-)

Where possible we try to expose default values in the data model. In this case you could expand the range and add a default statement on both of these leaves, for example:

leaf ibgp {
    type uint32 {
        range 1..256;
    }
    default 1;
    ...
}

You certainly can't have a default outside the range. So, even if you don't specify the default here, you need to expand the range to include the default.

type uint32 {
range 2..256;
}
configd:help "Maximum number of parallel eBGP paths to consider, default is 1.";
}
leaf ibgp {
type uint32 {
range 2..256;

Same as above - model default and extend range to include it.

}

}
}
}
