I wanted to share a DSL modem that is in bridge mode between two
FreeBSD boxes that make use of many VLANs on a pair of em
interfaces. In other words, I cant dedicate a physical interface to
just using the DSL. Normally, when creating vlans, I like to create them as so
/sbin/ifconfig em1.172 create 192.168.1.3/24
em1.172: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=3<RXCSUM,TXCSUM>
ether 00:30:48:d2:d6:11
inet 192.168.1.3 netmask 0xffffff00 broadcast 192.168.1.255
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
vlan: 172 parent interface: em1
However, if I try and bring up pppoe using em1.10 as the PPPoE
device, it does not work.

BUT, if I make the vlan device the "old way"
/sbin/ifconfig vlan172 create 192.168.1.3/24 vlandev em1 vlan 172
it works
It still complains about the other 2 interfaces, but it does not seem
to interfere with the PPPoE connection

Is there some reason this does not work ?
