Hello list, I have checked the implementation again and it seems ‘ipv4_has_link_scope()’ is not implemented: ipv6.h (everything works fine): 65 #define ipa_has_link_scope(x) ipv6_has_link_scope(&(x)) 90 static inline int ipv6_has_link_scope(ip_addr *a) 91 { 92 return ((a->addr[0] & 0xffc00000) == 0xfe800000); 93 } ipv4.h (returns 0 in any case) 59 #define ipa_has_link_scope(x) ipv4_has_link_scope(_I(x)) 77 static inline int ipv4_has_link_scope(u32 a UNUSED) 78 { 79 return 0; 80 } However, does it make sense to do this check in the first place? Thanks, Amadeus

I forgot to mention that my interface ‘784648196’ has an IPv4 scope link address configured like this:
784648196@NONE: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1462 qdisc pfifo_fast master bat0 state UNKNOWN group default qlen 1000 inet 169.254.40.2/21 scope link 784648196
How can I use scope link configurations with BGP in bird4?
Thanks again, Amadeus

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
