https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234472 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. -- You are receiving this mail because: You are the assignee for the bug.
