- else if (oi->state == ISM_InterfaceDown)
+ else if (oi->state == ISM_Down)

Probably because quagga-mpls isn't exactly 0.98.0, but quagga_0_98_stable
branch from CVS. This particular problem was regression introduced later
in development process and is already fixed in Quagga.

James, I volunteer to put together patch to update quagga-mpls to latest
quagga_0_98_stable code. Would it be OK? I will release Quagga 0.98.5 in
the beginning of the next week probably and would look it right after
that.
