https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234472 Andreas Pflug <pgadmin@pse-consulting.de> changed: What |Removed |Added ---------------------------------------------------------------------------- Severity|Affects Only Me |Affects Some People --- Comment #4 from Andreas Pflug <pgadmin@pse-consulting.de> --- After debugging a while, I found out that outgoing CARP packets are sent to= the expected MAC address 01:00:5e:00:00:12 with pf disabled, on some interfaces (those with gateways) instead of coding the lower 23bits of 224.0.0.18 into= the address some gateway on that local network is used. This is not conforming = to RFC1112 6.4, and apparently some IGMP aware switches will filter those malformed packets. In some case, flipping some IGMP instructions on switches affected may fix = CARP functionality, but the basic problem is in the freebsd kernel. --=20 You are receiving this mail because: You are the assignee for the bug.=
