When next-hop length is set to 16 bytes, and link-local capability is negotiated, we should send only link-local address and don't send GUA or an empty one (::). This was spotted using a datacenter profile. Fixes: 0050f82 ("bgpd: Send LL only if LL Next Hop capability is negotiated") Signed-off-by: Donatas Abraitis <donatas@opensourcerouting.org>
Fixes: 5f8ad40 ("bgpd: Show scope as link-local if using LL Next Hop capability") Signed-off-by: Donatas Abraitis <donatas@opensourcerouting.org>
