bird4 scope link

[Amadeus Alfa]

Hello list,

in bird6 I can use the following configuration snippet with IPv6 link local 
addresses:

protocol bgp xxx {
  neighbor fe80::2ff:c0bb:fe00:1234 % '784648196' as 1234;
};

('784648196' is the interface name)

My question is now: How can I use IPv4 scope link addresses in bird4?

When I use the line below I get an error: "Link-local address and interface 
scope must be used together"

protocol bgp xxx {
  neighbor 169.254.0.1 % '784648196' as 1234;
};

Thanks,
Amadeus
