Hello, I have the following configuration:
box1:/etc/rc.conf: | ifconfig_bge1="up" | ifconfig_vlan95="inet 10.9.128.2/20 vlan 95 vlandev bge1" | ifconfig_carp15="inet 10.9.128.1/32 vhid 15 pass secret advskew 100" | ifconfig_carp25="inet 10.9.128.1/32 vhid 25 pass secret" box2:/etc/rc.conf: | ifconfig_fxp0="up" | ifconfig_vlan95="inet 10.9.128.3/20 vlan 95 vlandev fxp1" | ifconfig_carp15="inet 10.9.128.1/32 vhid 15 pass secret" | ifconfig_carp25="inet 10.9.128.1/32 vhid 25 pass secret advskew 100" /etc/sysct.conf: | net.inet.carp.arpbalance=1 Output from ifconfig: box1: | carp15: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: BACKUP vhid 15 advbase 1 advskew 100 | carp25: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: MASTER vhid 25 advbase 1 advskew 0 box2: | carp15: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: MASTER vhid 15 advbase 1 advskew 0 | carp25: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: BACKUP vhid 25 advbase 1 advskew 100 Then, on box 1, I `ifconfig vlan95 down'. Updated output from ifconfig: box1: | carp15: flags=8<LOOPBACK> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: INIT vhid 15 advbase 1 advskew 100 | carp25: flags=8<LOOPBACK> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: INIT vhid 25 advbase 1 advskew 0 box2: | carp15: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: MASTER vhid 15 advbase 1 advskew 0 | carp25: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: MASTER vhid 25 advbase 1 advskew 100 Then, on box 1, I `ifconfig vlan95 up'. Again: box1: | carp15: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: BACKUP vhid 15 advbase 1 advskew 100 | carp25: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: BACKUP vhid 25 advbase 1 advskew 0 box2: | carp15: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: MASTER vhid 15 advbase 1 advskew 0 | carp25: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: MASTER vhid 25 advbase 1 advskew 100 Notice that both carp interfaces are running in "BACKUP" mode on box1, even after some period of waiting. I would expect things to return to the initial state. If I `tcpdump -i vlan95 vrrp' on both boxes at this point, I see: | 10:57:20.502188 IP 10.9.128.3 > VRRP.MCAST.NET: VRRPv2, Advertisement, | vrid 15, prio 0, authtype none, intvl 1s, length 36 | 10:57:21.503211 IP 10.9.128.3 > VRRP.MCAST.NET: VRRPv2, Advertisement, | vrid 15, prio 0, authtype none, intvl 1s, length 36 | 10:57:21.537201 IP 10.9.128.3 > VRRP.MCAST.NET: VRRPv2, Advertisement, | vrid 25, prio 100, authtype none, intvl 1s, length 36 | 10:57:22.504234 IP 10.9.128.3 > VRRP.MCAST.NET: VRRPv2, Advertisement, | vrid 15, prio 0, authtype none, intvl 1s, length 36 Note that box1 (10.9.128.2) isn't sending any advertisements. If I use the physical interface, not the vlan interface `ifconfig bge1 down' on box1: box1: | carp15: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: MASTER vhid 15 advbase 1 advskew 100 | carp25: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: MASTER vhid 25 advbase 1 advskew 0 box2: | carp16: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.144.1 netmask 0xffffffff | carp: MASTER vhid 16 advbase 1 advskew 0 | carp26: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.144.1 netmask 0xffffffff | carp: MASTER vhid 26 advbase 1 advskew 100 And finally, `ifconfig bge1 up' on box1: | carp15: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: BACKUP vhid 15 advbase 1 advskew 100 | carp25: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 | inet 10.9.128.1 netmask 0xffffffff | carp: MASTER vhid 25 advbase 1 advskew 0 Things return to where they should be.
