Hello Martin
before I go further - I just run a ping test with the tcpdump as you
requested and it did work. The only thing that was changed was an
upgrade from GENERIC.MP#1983 -> GENERIC.MP#1997.

Do you mean the CARP node does not answer to ping with a destination
address on the carp(4) interfaces? Is it for MASTER, BACKUP or both?
em2 (no ip) ---> vlan100 (192.168.150.200) ---> carp2 (192.168.150.1)
\
--> vlan101 (192.168.151.200) ---> carp3 (192.168.151.1)
This is my setup
if I ping either address assigned to carp2 or carp3 from a host on the
network I do not get an answer, pinging the vlan address answers.
When doing so, please use "# tcpdump -nvei carp2 icmp" to see if the
echo request/reply reach/leave the interface.
One node is clearly in MASTER, the other in BACKUP, demote works.
The routing table correspond to which node? MASTER or BACKUP? There's
something really weird in it, the RTF_CLONING routes are done.
The table was from the MASTER.
What do you mean exactly by 'the RTF_CLONING routes are done.'? I read
route(4) and if I understand it correctly a wildcard route such as
defaults is marked with it and new routes are created as soon as they
are used and marked as RTF)CLONED.
Could you include your whole routing table? Do you have an entry for
the machine initiating the ping?
The host also has two further carp interfaces sitting directly on a physical
interface which work as expected.
Then why excluding this information from the table?
Here is the entire routing table (be warned it is 'long')
# route -n show -inet
