So, the template just waits all traffic to stop. > On Mon, Aug 26, 2019 at 2:05 PM Abhijeet Rastogi <abhijeet.1...@gmail.com> > wrote: > > Now that you said, if it's not happening it should be a bug, looks like I > > missed seeing a key section in the ipvsadm output. > > > > FWM 97284778 IPv6 rr persistent 120 > > -> [v6_reals:9222]:0 Route 1 0 0 > > -> [v6_reals:9223]:0 Route 1 0 0 > > -> [v6_reals:9224]:0 Route 1 0 0 > > > > There is no mask mentioned in the service table info (line1).

For example: ipvsadm -A -f FWMARK -6 -s rr -p 120 -M 48 Is it working this way? http://kb.linuxvirtualserver.org/wiki/IPv6_load_balancing May be the ipvsadm man page should have example for -6.
