bird4 scope link

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
