I have a problem with CARP on FreeBSD 6.2 in the following scheme:
+--------------+ +-----------------------+ +-----------------+
| A | | B | | C |
| vlan20 |-//->| vlan20 vlan10 |-//--| vlan10 |
+--------------+ +-----------------------+ +-----------------+
vlan20 10.10.10.2/26 vlan20 10.10.10.1/26
gateway 10.10.10.1 vlan10 10.10.9.1/26 vlan10 10.10.9.2/26
carp10 10.10.9.3/26 carp10 10.10.9.3/26
advskew 0 advskew 1
carp11 10.10.9.4/26 carp11 10.10.9.4/26
advskew 1 advskew 0
i.e. server B - MASTER for 10.10.9.3/26, BACKUP for 10.10.9.4/26
server C - BACKUP for 10.10.9.3/26, MASTER for 10.10.9.4/26
But if to send icmp request from server A -> to server C on ip 10.10.9.4,
server B reply from BACKUP iface carp11 !?!?
This is trouble or feature of realization ?????
-------------------------------------------------
serverB> ifconfig carp*
carp10: flags=49<UP,LOOPBACK,RUNNING> mtu 1500
inet 10.10.9.3 netmask 0xffffffc0
carp: MASTER vhid 100 advbase 1 advskew 0
carp11: flags=49<UP,LOOPBACK,RUNNING> mtu 1500
inet 10.10.9.4 netmask 0xffffffc0
carp: BACKUP vhid 101 advbase 1 advskew 1
serverC> ifconfig carp*
carp10: flags=49<UP,LOOPBACK,RUNNING> mtu 1500
inet 10.10.9.3 netmask 0xffffffc0
carp: BACKUP vhid 100 advbase 1 advskew 1
carp11: flags=49<UP,LOOPBACK,RUNNING> mtu 1500
inet 10.10.9.4 netmask 0xffffffc0
carp: MASTER vhid 101 advbase 1 advskew 0
Tell please when will be an option "carpdev" in FreeBSD?
Thanks...
