Folks,

While doing some testing, it seems that FreeBSD ignores ICMPv6 Redirects
when both the Redirect Destination and the Redirect Target are the same
(i.e., the destination is supposed to be on-link).

OTOH, Redirects are processed as expected when the Redirect Target is
different from the Redirect Destination.

Should I report this as a bug, or is this (non-rfc-compliant) behavior
intentional? (If so, what's the rationale?)

Thanks!

Best regards,
