A question about disabling sending redirects in IPV6 (versus IPV4)

Hello,

I have a question regarding disabling sending redirects in IPV6 in the
linux kernel:

In include/linux/ipv6.h, I see a member called accept_redirects in
ipv6_devconf,
but there is no send_redirects member.

There is /proc/sys/net/ipv6/conf/all/accept_redirects but
I could not find /proc/sys/net/ipv6/conf/all/send_redirects.

(In IPV4 there is both /proc/sys/net/ipv4/conf/all/send_redirects and
/proc/sys/net/ipv4/conf/all/accept_redirects).

Is there some reason that there is no way (as far as I understand)
to disable sending redirects in IPV6 ? Why there is a way to do it in IPV4
and there is no way to do it in IPV6?

Regards,


Ian
