I have 2 addresses on the interface in this case.
vl-foo up (index=22 master=foo)
MultiAccess Broadcast Multicast AdminUp LinkUp MTU=1500
100.63.16.4/21 (Preferred, scope univ)
192.168.1.5/24 (scope site)
fe80::4d8:7ff:fe73:68b6/64 (Preferred, scope link)
The idea is that the primary range, 100.x.x.x, is used for OSPF between nodes
on the VLAN, and the secondary address is to emulate a legacy device, where the
same address is needed on multiple VLANs. The secondary address isn't actually
involved here, but I don't see a way in the documentation to limit it to only
sending out with the primary address.
