Avoid using RFC3927 outside of the link

[Alarig Le Lay]

Hi,

I have a router that is mutli-homed with BGP. One of my peers is using
an RFC3927 address for the connection. If I traceroute to host behind
that route where we use a route via this peer to reply, the ICMP reply
display that link-local IP:

  1. AS12876 195-154-86-1.rev.poneytelecom.eu (195.154.86.1)     0.0%    10    
0.9   0.8   0.6   1.1   0.0
  2. AS12876 a9k2-49e-s46-3.dc3.poneytelecom.eu (195.154.1.86)   0.0%    10    
0.8   1.1   0.7   2.2   0.5
  3. AS12876 pni-th2-a9k2.th2.poneytelecom.eu (195.154.1.75)     0.0%    10

  6. AS???   169.254.1.2                                         0.0%    10

  7. AS204092kaiminus.swordarmor.fr (89.234.186.26)              0.0%    10    
8.1  11.4   7.8  41.5  10.6

Is it possible to avoid this behaviour and reply with the public IP
(89.234.186.1) instead? What I am looking for is an equivalent of `ip
addr change 169.254.1.2/30 scope link` on Linux.

Thanks,
