When upgrading Debian system to latest version (Trixie), with the backported kernel,
we can notice a highly unusual amount of log lines stating "icmp: detected local route for xx"
are present inside of dmesg.

This seem to be a similar issue to the one happening in an other bug report, but which was linked to a much older kernel version (#1135514), and is now considered resolved.

The problem also happens when running Debian Bookworm, and the latest backported kernel versions. This is true for at least the version "6.12.85+deb12-amd64" but is perhaps not limited to it.

Hi,

Can you please followup to this bug including the information
collected by reportbug's bugscript? In particular we will need some
more details on how your setup look at and steps triggering the issue.

Does the above imply that you only are reproducing the issue with the
bpo variants in each suite? I assume not, but the information was not
entirely clear to me.

Regards,
Salvatore
