Description Enji Cooper freebsd_committer 2012-08-22 04:00:22 UTC
Setting up static IPv6 addresses with vlan interfaces is broken on 9.0-RELEASE (the link local address is set via rc(5), but not the IPv6 static address). Example:

# cat /etc/rc.conf 
hostname="wf048.west.isilon.com"
loctet=1

: ${mtu=9000}
: ${vlan_mtu=9000}

vlans_cxgb1="223"
ifconfig_cxgb1="inet 192.168.21.$loctet/24 mtu $mtu vlanmtu $vlan_mtu $cap"
ifconfig_cxgb1_223="inet 192.168.20.$loctet/24"
case "$(uname -r)" in
9*|1[0-9]*)
        ifconfig_cxgb1_ipv6="inet6 fec0::00:d3:ad:b3:3f:0$loctet prefixlen 24"
        ifconfig_cxgb1_223_ipv6="inet6 fec0::01:d3:ad:b3:3f:0$loctet prefixlen 22

Manually configuring the vlan interface with ifconfig works though, so it's an rc(5) problem, as suspected earlier:


wf048# ifconfig cxgb1.223 inet6 fec0::01:d3:ad:b3:3f:01 prefixlen 24
wf048# ifconfig cxgb1.223

        inet 192.168.20.1 netmask 0xffffff00 broadcast 192.168.20.255
        inet6 fe80::207:43ff:fe07:3f71%cxgb1.223 prefixlen 64 scopeid 0xe 
        inet6 fec0:0:1:d3:ad:b3:3f:1 prefixlen 24 
        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
        media: Ethernet 10Gbase-SR <full-duplex>
        status: active
        vlan: 223 parent interface: cxgb1

How-To-Repeat: # cat >> /etc/rc.conf <<EOF
interface=cxgb1 # Change this.
vlan=223
vlans_${interface}="$vlan"
ifconfig_${interface}_ipv6="inet6 fec0::00:d3:ad:b3:3f:01 prefixlen 24"
ifconfig_${interface}_${vlan}_ipv6="inet6 fec0::01:d3:ad:b3:3f:01 prefixlen 24"

# service netif restart cxgb1
