I don't think the code is going to like interface name != vif-name.  There seem to be
lots of assumptions that they are always the same.  Maybe it's time to rip out that
code once and for all, and just make everything a vif.

For this particular error, it might be using eth1's info (name, or perhaps if-index)
instead of eth1.100

It's also possible that there is a race and eth1.100 either isn't in the kernel yet, or
hasn't been discovered by xorp.

What version of xorp are you using?  Latest xorp.ct from git tree?

Thanks,
Ben
