----------------
i replaced the network part with x.x.x for privacy reasons
x.x.x.212 is an EdgeCore L3 switch running OSPF.
x.x.x.240 is an end-user being routed
all of this is done over eth0.1, which has 4 VLAN created and up (eth0.1
eth0.2 eth0 eth0.4 eth0.21)
eth0 Link encap:Ethernet HWaddr 00:11:D8:D4:A8:8C

also note that the "native" vlan on eth0 is 3 so using eth0.1 is
definately correct in this case. this cannot be changed for legacy reasons
this doesn't happen on other systems that don't use VLANs, and combined
with the reference below, lead me to think it really is vlan related
