Created attachment 484332 [details] This patch fixes the ttl defaults and range This patch fixes the ttl defaults and range 1) both IPv4 and IPv6 mcast should default to ttl=1 2) the range should be 0..255 0 is valid meaning localhost only (cluster of one) I have confirmed: corosync starts up with ttl=0, tt=4 & ttl=255 corosync errors with -1 and 256
