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=
1.2 1.5 1.1 3.5 0.6
4. AS??? equinix-th2.quantic-telecom.net (195.42.144.192) 0.0% 10=
1.1 1.0 0.9 1.2 0.0
5. AS198507185.132.75.33 0.0% 10=
7.3 7.4 7.2 7.9 0.0
6. AS??? 169.254.1.2 0.0% 10=
7.6 7.6 7.4 7.9 0.0
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,
